  1. Turning a Functional Cloth into an Actuator by Combining Thread-like Thin Artificial Muscles and Embroidery Techniques Reviewed International journal

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:IEEE Robotics and Automation Letters  

    In recent decades, a few cloth-type actuators have been developed. One of these is a type of textile in which strings and artificial muscles are woven together; another type is made by weaving artificial muscles into a pre-made fabric. These devices have a limited choice of cloths that can be actuated; thus, in this paper, we propose to turn various existing cloths, especially functional cloths, into actuators. We create a prototypical actuator that can be deformed in three dimensions using thin artificial muscles and embroidery techniques on a functional cloth used for hook-and-loop fasteners and textiles that can observe pressure. Our experimental results indicate that the force of the artificial muscles can be transmitted to the cloth using fixation by embroidery and that the actuator can be variously deformed in three dimensions. We show that functional cloths can be made into actuators while maintaining their own functions using the proposed method.

    Dual three-phase permanent magnet synchronous motors have the characteristics of multi-phase and permanent magnet synchronous motors, whose double- and decoupled-winding models based on the vector space decomposition have been reported. High-frequency signal injection methods enable position sensorless control, parameter identification, and the search for maximum torque per ampere operating points. However, the current control system with high-frequency signal injection for a dual three-phase permanent magnet synchronous motor has not yet been sufficiently discussed. This study compares the double- and decoupled-winding models for the current control system with the high-frequency signal injection and proposes a current control system with high-frequency signal injection. Furthermore, this study proposes a position sensorless control method at low speed based on the high-frequency voltage injection as an application of the proposed current control system with the high-frequency signal injection. Experiments verify the effectiveness of the proposed current control system with the high-frequency signal injection and the proposed position sensorless control method.

    This paper evaluates the performance of contact force-based control with developed wearable assistive robots enabling the contact force measurement between the wearer and the robot. Almost all the conventional assistive robots are controlled with their joint torque measured via torque sensors. These robots have risks exerting excessive force on the wearer because torque sensors cannot detect contact force exerting the wearer. Our research group developed the contact force-based control and evaluated its performance only on the simulation. Also, we developed a prototype of a wearable robot enabling to measure and detect the contact force. In this paper, tracking performance to the wearer's movements, one of the basic performances of wearable robots, is confirmed via the experience. As a result, contact force-based control can operate in full accordance with the command of zero contact force.

    This paper proposes a method to drive a single-inverter dual interior permanent magnet synchronous motor (IPMSM) system by using signal injection. Considerable research has been performed to decrease the size and cost of dual motor drive systems by driving two synchronous motors with one inverter. In general, the control is implemented considering one of the two motors. Such systems may become unstable because of the mechanical/electrical resonance occurring in the uncontrolled motor. Therefore, methods to suppress this resonance have been established. Notably, resonance control is challenging to implement at low speeds because the phase of the rotor with sensorless control cannot be easily estimated. To address this problem, signal injection and signal processing methods for such systems was established in this study.

    Extended electro-motive force (EEMF) estimation method is a fast position estimation method used for overall speed. In our previous research, we have reported the startup and drive method with EEMF from standstill. However, starting a free-running PMSM, which is known as the flying start, is rarely taken into consideration in the most position sensorless research. Under such condition, the rotor speed is unobservable before the startup. In this paper, a startup and driving strategy at overall speed with EEMF by speed and signal injection is proposed, and the evaluation experiments are reported.

    The authors have been aiming to realize a remote driving system with an HMD(Head Mounted Display) and a 360-degree camera to decrease the task load of the operator. Therefore, we have been tackling an operator assistance method of remote driving applying Augmented Reality(AR). In the previously proposed methods, AR video presented to the operator is generated based on sensing information of 3D LiDAR to deal with the communication delay. In this paper, a new generation method of AR image is proposed, in which Gaze information of the operator is used to create a 3D object to draw his attention to a hazard that might cause a traffic accident. The usefulness of the proposed method has been evaluated based on the results of the experiments using a driving simulator which has a scenario of a person jumping out from a park.

    To realize automated drive of a vehicle, more reliability to the motor drive system is required. The three phase dual winding permanent magnet motor drive using two inverters with corresponding voltage supplies is one of the potential candidates for the reliable motor drive system. With the respective voltage supply and winding connected to the inverter, the two motor drive systems are electrically independent. Thus, even if when a failure occurs in one of the systems, the other system can continue the motor drive. However, there is an issue: a voltage drop in one of the voltage supplies reduces the sinusoidal wave region of the drive system as the rotor of the motor is common in the two windings and the back electromotive voltage in the two windings are the same. The motor drive method that enlarges the applied voltage without causing high harmonics under the voltage supply unbalance in the three phase dual winding permanent magnet motor is proposed in this paper.

    According to the increase in the required performance of the product, a multi-core processor that can process tasks simultaneously is attracting attention. To efficiently utilize a multi-core processor, a Model-Based Parallelization Tool(MBP) technology has been proposed to automatically generate paral-lelization code in consideration of the causal relationship of the control system. However, parallel processing time and control performance verification in real systems have not been sufficiently investigated. In this paper, to verify the validity of the parallelization code automatically generated by the MBP on a real system, we compare and review the single-code of the function unit by hand and the parallel code automatically generated by the MBP. In addition, we verify the MBP Tool by analyzing parallelization results as well as points to consider when implementing a motor control system.

    A direct speed control strategy based on finite control set model predictive control (FCSMPC) with a voltage smoother is presented herein. In the proposed concept, a finite set of smoothed voltage vectors characterized by an adjustable amplitude and a movable origin is introduced as voltage candidates in the FCSMPC scheme. The controller predicts the future current and speed and outputs the optimal smoothed voltage using pulse-width modulation. Owing to this control scheme, an abrupt change in the output voltage, which causes a large current ripple, is avoided without additional computational costs. Simulation and experimental results obtained using a permanent magnet synchronous motor fed by a two-level three-phase inverter show that the proposed method effectively reduces the current ripple while achieving a high dynamic drive compared with the conventional FCSMPC scheme.

    In this paper, we propose a novel discrete current control scheme for IM (Inductive Motor). Ordinary, a current vector controller is designed by using the dq-axis model, which is induced under the assumption that Park transformation is continuously performed, and the designed controller is discretely implimented. If the sampling period is not short enough compared to the voltage supply frequency during high speed drive, these assumptions do not hold, and the control performance of the current system is greatly degraded, which results in control failure. To solve this problem, we proposed a discrete dq-axis IM model which is effective for low control period and high speed drive, and designed a current vector controller based on this model to improve control performance at high speed drive and confirmed the effect in simulation.

    The authors have been tackling a new teleoperation system with a head-mounted display (HMD) and an omnidirectional camera to reduce the workload of an operator. Some experimental results verified that presentation of AR images based on sensor information could reduce the workload and prevent the deterioration of the task quality due to the transmission delay of images. However, the range of the field of view (FOV) of an HMD is narrower than that of a human. This difference might cause accidents by overlooking hazards that are outside the FOV of the HMD. To solve this problem, the authors propose a new method of AR image presentation based on gaze information not to overlook hazards. Some experimental results using a driving simulator verified the usefulness of the proposed method.

    Synchronous reluctance motors (SynRMs) have attracted attention for various applications because they have no magnets and rotor windings. Thus, various methods for rotor position sensorless control of SynRMs at low speeds have been proposed. Similarly, we previously introduced a method for rotor position sensorless control of SynRMs at very low speeds. The proposed control method superimposes a high-frequency current with a small constant amplitude using a high-frequency current control system. The q-axis inductance of the SynRM considerably changes according to the load. In this paper, we show that the rotor position estimation error converges even under a large error between the predefined and real settings of the q-axis inductance of the SynRM model for position estimation when using the proposed method. Experimental results confirm that the proposed method achieves robust rotor position sensorless control against q-axis inductance variations even at very low speeds.

    This paper proposes a capacitor current reduction method using real-time model predictive control (MPC) for a double three-phase permanent magnet synchronous motor (DTPPMSM) drive system. Capacitor current reduction for volume minimization of DTP-PMSM drive system is important issue. Optimizing switching timings by MPC is promising approach. However, it is difficult to implement ideal MPC in a real system because it requires a huge amount of calculation to predict the capacitor current. In this paper, we propose a new method that is possible to search optimal switching timing for reducing the capacitor current by using the MPC, whose calculation amount can be implemented in real-time. This paper shows the possibility of realizing an capacitor current reduction method with high control performance by reducing the amount of computation for MPC.

    In order to realize a remote car driving in an emergency situation or complicated environment, we propose a new method for operator support in teleoperation in this paper. In the proposed teleoperation system, it is supposed that there are two communication lines between an operator and the target remote driving car. The one is called as the main line, in which large data like image or sound are transferred allowing a large delay. The other is called as the subline, in which small data like emergency signals are transferred with a small delay. In the proposed method, an AR image is presented to an operator, in which 3D objects superimposed on a real image are generated using sensor data transferred through the subline. Due to the 3D objects with a small delay on a real image with a large delay, the operator can safely control the target car even if the image has an enormous delay caused by the bad communication status.

    We have proposed a modeling method of human actions based on the causality between a situation and an action. In this method, a human action rule is expressed by an If-the-rule style, assumed that a person changes his current action to the next one according to the situation around him. In the previous method, a human action and a situation in a human action rule is modeled with a Hidden Markov Model(HMM). HMM is one of powerful tools for modeling time series data, but it ignores the change speed of time series data. In addition, time series data on human actions and situations are classified by Continuous Dynamic Programming. This means that two types of criteria should be set for modeling. In order to overcome these problems, we propose a new modeling method of human actions with Hidden Semi-Markov Model(HSMM) in this paper. In the proposed method, both clustering and modeling of time series data are executed with HSMM. The usefulness of the proposed method is discussed through some modeling results of human actions on operating a radio-controlled vehicle.

    In this paper, we propose a new teleoperation system of a mobile robot using Augmented Reality(AR) based on 3D LiDAR information for operator support. In the proposed system, an 360-degree camera is equipped with a robot which works in a remote place controlled by an operator, and the captured 360-degree image is displayed to the head mounted display put on the head of the operator. The operator can smoothly control the robot watching what he needs for his task by turning his head. In addition, the provided image around the robot has no blind spot because of the 360-degree image. However, the data size of the 360-degree image is enormous and it causes a large transfer delay or dropped frames which adversely influence the operator performance. In order to solve this problem, it is proposed that an AR image is actually provided to the operator, in which objects generated based on 3D LiDAR information are superimposed on the 360-degree image as AR objects. In this paper, the usefulness of the proposed method is shown through the experimental results on parking the robot remotely.

    More reliable motor drive systems are expected in the realization of automated driving. The redundant motor drive system with two voltage supplies, two inverters, and a dual winding motor is one of the strong candidates since the two systems that construct the motor drive system are electrically independent. The dual winding motor has a characteristic of cancelling the 6th harmonic produced in the overmodulation drive. However, it loses its characteristic when there is a voltage difference in the two voltage supplies. In this paper, it is proposed to control only the sum of the current during the overmodulation to maintain the characteristic of cancellation even if there is voltage difference in the two voltage supplies. Furthermore, the current difference of the two windings is controlled in the sinusoidal wave region to suppress the deviation of currents and turned off during the overmodulation to reduce 6th harmonic. The maintained characteristic during voltage supply unbalance is confirmed with the experiment.

    A novel decoupling control scheme for multiphase machines with multiple three-phase winding sets, for instance, the Dual Three Phase (DTP) machines, is proposed in this paper. This motor has two sets of three phase windings that implemented spatially with 30 electrical degrees. Vector Space Decomposition (VSD) frame and Multiple Stator (MS) frame are well known for its vector control. VSD frame has been applied in many applications due to its clear harmonics mapping and good extensions to multiphase machines. On the other hand, MS frame is more intuitive as to treat two winding sets individually so that the accumulated techniques of three-phase machines can be applied directly. However, this approach was not adopted in high performance drives because its decoupling control methodology is not sufficiently developed to solve its inherent magnetic coupling issue. Therefore, this paper proposed a decoupling control scheme to improve dynamic performance of MS frame, and performance has been evaluated by experimental results.

    The scope of embedded systems used by multi-core processors is widely applied to various products that require control, such as home appliances, industrial devices, transportation devices, and communication terminals. Model-Base Parallelization technology was proposed towards efficient parallelization to implement a control system in the introduction of multi-core processors. By applying MBP, it is possible to parallelization even details that people are not aware of, but the control system with numerous causal relationships still does not sufficiently utilize multi-core. Therefore, a method of inserting a time-delay is being studied as a method for improving the parallelization of multi-cores.In this paper, We describe the insertion location that improves parallelization and does not affect the control performance by inserting time-delay to implement the vector control system of PMSM on multi-core efficiently.

    This paper describes the design method for Model Predictive Control (MPC) that is suitable for current control systems of Permanent Magnet Synchronous Motor (PMSM). A current control system based on MPC predicts future current behaviors for considerable input voltage and determines the optimum input voltage by evaluating these behaviors. Conventional MPC sets the cost function, making it effective for several control purposes. However, the suitability of the search space of conventional MPC has not been discussed and its achievable performance was limited. In this paper, we consider an appropriate search space for current control system of PMSM by referring to existing modulation methods and inverter operation. Then, we propose new MPC that satisfies that search space and show that the proposed MPC can usage from a linear region to a square-wave region by the appropriate search space.

However, the basic MPC has inferior steady current control performance depending on the operating points. This is because the search space of basic MPC represented by voltage vectors is not suitable appropriate for PMSM current control. To overcome this problem, we consider difference of search space of basic MPC and current vector control with a modulator such as Pulse Width Modulation (PWM) or Space Vector Modulation (SVM) and clarify the necessary search space for improving the steady current control performance. Then we propose a design method for the search space, and through experimentation, we show that proposed design method can improve the steady current control performance.

    Synchronous reluctance motors (SynRMs) have attracted much attention because they do not require magnets. Position sensorless control of SynRMs at low speeds is necessary, and several methods have been proposed in this regard. A new position sensorless control method for SynRMs operating in the very low-speed region is proposed. This approach superimposes a high-frequency current with a small and constant amplitude and a constant frequency to the torque current for driving the SynRMs, by using a high-frequency current control system. It has been shown that robust position sensorless control against inductance variations can be realized using this proposed method. In the position sensorless control method based on a superimposing signal, the current should be small. Therefore, in this paper, the capability of the presented approach to achieve a minimum constant amplitude of the high-frequency current is investigated. The experimental results indicate that the proposed method is a feasible one as position sensorless control of SynRMs in very-low speed region even if the superimposed current has a minimum constant amplitude.

    A flux model that can easily achieve both maximum torque per ampere (MTPA) control and position sensorless control of interior permanent magnet synchronous motors (IPMSMs), is proposed herein. Flux is proposed to be estimated using a full-order observer whose pole assignment is difficult because the order of the error equations of the observer becomes four, and the pole assignment of the full-order observer is proposed. This pole assignment of the full-order observer, in which robust flux estimation against velocity estimation error become possible, is obtained by solving a ?-positive real problem and a H8 control problem. Herein, the experimental result of the position sensorless control of IPMSMs indicates that the proposed pole assignment of the full-order observer is highly useful and can be used to realize MTPA control.

    There are many mathematical models for the position sensorless control of permanent magnet synchronous motors (PMSMs), and various position sensorless control methods have already proposed. However, it is necessary to select a control model according to the objective from characteristics of the EMF phase and the robustness against to the motor parameters. An Imaginary Electromotive Force (IEMF) expression can clarify the differences of these models. This paper discusses the characteristics of each model including the Extended Electromotive Force model for position sensorless control that can be applied to the standstill / low speed range from the middle / high speed range. Finally, we show that this IEMF expression is extremely useful in discussing and designing characteristics of the control models of PMSMs.

    This paper describes a new discrete-time PMSM model for the discrete design of current vector control systems. The discrete design of current control system minimizes the discretization error and improves the current control performance at the sampling point. The conventional PMSM model discretization method presumes that park transformation runs continuously. When the sampling frequency is considerably lower than the fundamental electric frequency, this assumption is invalid and the control performance will degrade due to modeling error. In this paper, the authors propose a method of PMSM model discretization considering discrete-time park transformation and design an additional cross-coupling compensator for the proposed model. The experimetntation results demonstrate the effectiveness of the proposed model.

    This paper presents signal conditions taking motor efficiency into account for position sensorless control of interior permanent magnet synchronous motors (IPMSMs). Signal injection is necessary for position estimation based on an extended electromotive force (EEMF) model at standstill and low speeds. We have proposed a maximum torque control reference frame and the EEMF model suitable for signal injection, and we executed sensorless control in the entire driving area. However, its effects on motor efficiency have not been evaluated in the previous study. Therefore, in this paper, we optimize the amplitude, phase, and frequency of signal current. Moreover, we applied a signal current amplitude adjusting method. This method makes the signal current amplitude minimum based on the EEMF. As a result, we can maintain constant efficiency including copper loss and other losses of the motor, regardless of the signal frequency. The signal frequency can be freely selected in terms of the motor efficiency, so that the proposed method can improve the flexibility to design the injection signals for the position sensorless control of the IPMSMs.

    To realize the neutral point potential (NPP) control for three-level neutral-point-clamped (TL-NPC) converters, a novel NPP control based on the search optimization method of the two degrees of freedom is proposed in this paper. It can overcome the low-frequency NPP fluctuation problem that appears under nearest-three-vector pulse width modulation (PWM)-based NPP control under some operating conditions. Although the traditional dual modulation wave method can also solve the low-frequency NPP problem, the zero-sequence voltage is limited under this modulation. It decreases the control domain of the neutral point current (io), which causes serious NPP drift problem especially in some special operating conditions, such as a long dead time, a strong asymmetrical load, or serious switch device inconsistency. The proposed method can expand the control domain of io by defining a new degree of freedom, thus lifting the limits of the zero-sequence voltage and searching for the optimal two degrees of freedom. The wider control domain of io corresponds to a stronger NPP control ability. Experiments are carried out finally to prove the merits of the proposed method, by comparing the switching frequency, the NPP control speed, and the output performance. © 2018 Institute of Electrical Engineers of Japan.

    This paper presents the filter setting for improving the current control performance of IPMSMs in overmodulation region of inverter. To operate IPMSMs in the overmodulation region, it is necessary to deal with harmonic components. Generally, harmonics suppression method based on harmonics current model is utilized to deal with these components, however, it requires accurate motor parameters. In this paper, Band Stop Filter is utilized to suppress the harmonic components, and weight averaging method is applied to improve the current responses, without any motor parameter. Simulation results are demonstrated to show the current control performance and the operation range of proposed method.

    With an increase in the elderly population, traffic accidents caused by elderly drivers have become an important social issue in Japan. The primary factor of traffic accidents by elderly drivers is a reduction in their driving skill. Therefore, elderly drivers are required by law to conduct regularly a driving aptitude test in Japan. If the driving skill of the driver is inadequacy, he is subject to punishment, such as driver license revoked. However, there is not appropriate evaluation index of driving skill. We have proposed a modeling method of driving behavior to support one. Proposed driving behavior model is generated based on the actual driving data of driver, and the generated model has some kind of habit and pattern of the driver. Therefore, it is considered that it is possible to evaluate driving skill of a driver by analyzing the generated model. According this reason, we aim to propose a modeling method of driving behavior to evaluate driving skill. Here, a coincident timing skill of driver is focused as a driving skill. In the case of driving behavior, the execution timing of driving operations is decided based on the prediction of subsequent change of the outside environment information. The accuracy of this decided execution timing of operation depend on the above prediction is called as the coincident timing skill. In the proposed model, the causality between the situation around a person and operation of driver is modeled by Hidden Markov Model, and timing probability distribution is added to Hidden Markov Model in order to evaluate this coincident timing skill. The timing probability distribution expresses the execution timing of next operation of driver. Therefore, it is possible to detect the information of the coincident timing skill of driver from the timing probability distribution. In the experiment, the controller operation of a radio controlled vehicle is modeled by the proposed method, and the usefulness of the proposed model is examined through some experimental results.

    Sensorless control based on a pattern matching method is proposed for interior permanent magnet synchronous motors (IPMSMs), which have non-sinusoidal inductance spatial distribution at a standstill and very low speed regions. By using the pattern matching method, closed-loop-position sensorless control is possible for IPMSMs even under the heavy load condition, but atypical position error occurs. A previous study examined why position control errors are generated in the pattern matching method. This paper presents three improvement methods for the position control error by considering the cause of the position control error. In addition, characteristics of each proposed method are clearly explained, and their effectiveness is presented by simulation and experimental results.

    A sensorless control based on a pattern matching method is proposed for interior permanent magnet synchronous motors which have non-sinusoidal inductance spatial distribution, at a standstill and in very-low-speed regions. A previous study indicated that closed-loop-position sensorless control can be achieved under heavy load conditions. However, position control errors are generated at atypical rotor positions, and the reason for this has not been clarified. Moreover, there remains an issue in which this position error cannot be perceived before position sensorless control is carried out. This study examines why position control errors are generated in the pattern matching method. Furthermore, an evaluation method that estimates position control error in advance is proposed using the clarified mechanism of position error generation. The effectiveness of the proposed method is demonstrated by comparing experimental and evaluation results.

    This paper proposes a filter design for improving the control performance of the current control system of Permanent Magnet Synchronous Motors (PMSMs) using the overmodulation region of an inverter. The control performance of a vector control system for PMSMs using the overmodulation region of an inverter can be improved by suppressing harmonic components that are generated in this region. This paper utilizes Band Elimination Filter (BEF) to eliminate harmonic components; however, unsuitable BEF setting leads to generation of large current oscillation at the resonant frequency of current feedback loop with BEF. In order to deal with these problems, the proposed filter design focuses on gain setting at the cutoff frequency of BEF. The proposed filter design can prevent the generation of current oscillation at the resonant frequency of the system, and can improve current control performance without complex adjustments. Simulations and experiments are carried out to show the effectiveness of the proposed BEF setting.

    For the discussion about the neutral point potential (NPP) control of single phase three-level rectifiers, most of the methods solve the NPP problem by adjusting the zero-sequence voltage under symmetrical load conditions. However, when one phase voltage reaches to the maximum voltage, the other phase voltage goes to the minimal voltage. As a result, the NPP control ability is limited since there is no chosen zero-sequence voltage when the modulation ratio is close to 1. It can not be suitable for some strong asymmetrical load applications, in which two DC-link capacitors are used to drive different loads separately. In this paper, a dual-degrees of freedom based PWM is proposed, which can enhance the NPP control ability for single phase three level rectifiers. Introducing a new degree of freedom, the proposed method has more choices for the NPP control. It can decrease the NPP fluctuation under the strong asymmetrical load conditions, compared with the traditional PWM methods. The simulation results ratify the correctness and feasibility of the proposed PWM method finally.

    Even though the neutral point potential (NPP) balance problem of three-level neutral-point-clamped (NPC) converters can be solved by the traditional methods based on nearest-three-vectors (NTV) PWM, a low frequency fluctuation in the NPP will appear, which makes the capacitor reduction become hard. The dual modulation waves method is used to overcome the low frequency fluctuation, but it is an open-loop way, which will cause the drift voltage problem of the NPP and increase the switching frequency. Moreover, the control ability of the neutral point current is limited since the zero-sequence voltage is fixed. By removing the limit of the zero-sequence voltage and introducing a new degree of freedom, a novel NPP control of three-level NPC converters based on the search optimization is proposed in this paper. Fuzzing the boundary between the NTV-PWM and the dual modulation waves method, the proposed method realizes two modulations by a unified way. It can solve the low frequency fluctuation problem, reduce the switching frequency and extend the control ability of the neutral point current simultaneously by choosing the optimal dual degrees of freedom. Comparing the NTV-PWM, the dual modulation waves method and the proposed method, the simulation results verify the correctness and effectiveness of the proposed method.

    This paper presents a novel pattern matching based position sensorless control method for IPMSMs. A target IPMSM for the proposed method is designed such that it has high power and torque density, while also being significantly influenced by magnetic saturation. As previously reported in papers , for IPMSMs, heavy magnetic saturation affects the spatial distribution of phase inductances according to rotor positions. Most position sensorless controls at low speeds typically depend on the assumption that phase inductances have sinusoidal spatial distribution according to rotor positions. Therefore, it is difficult to apply conventional methods to IPMSMs with heavy magnetic saturation. In the proposed method, rotor position is estimated by pattern matching using feature values, so that the phase inductances have unique and reproducible value according to rotor positions. While template data sets are required for the proposed method, the assumption for sinusoidal phase inductances is not. In this paper, the effect of magnetic saturation for position estimation based on conventional methods is discussed in Section 1 and 2. Then, details of the proposed method are shown in Section 3. In Section 4, results of experiments carried out in steady state and transient state are presented. The effectiveness of the proposed method is verified through the experiments.

    Several position sensorless control methods of IPMSMs(Interior Permanent Magnet Synchronous Motors) using the observers have been proposed. In case of the full-order observers, these designs are difficult, because the order of the error equations of the observers becomes four. In this paper, for the position sensorless control of IPMSMs, a design method of the full-order observer based on the extended electromotive force (EEMF) is proposed. The experimental result shows that this design method of full-order observer is very useful.

    Even though some methods have been put forward to solve the drift problem and the low frequency fluctuation problem of the neutral point potential (NPP) for three level neutral point clamped converters (TL-NPC), they are all just suitable for SPWM or SVPWM technologies. In some medium/high voltage high power applications, where SHEPWM is utilized to modulate the reference voltages, the drift problem and the low frequency fluctuation problem of the NPP become difficult. The duty cycle of phase voltage waveforms under SHEPWM can't be adjusted after the switching angles were calculated based on the optimal harmonic limits. For the severe low frequency fluctuation of the NPP, a suppression method is raised based on 3-order harmonic amendment in this paper. 3-order harmonic has no effect on the output performances under 3-phase 3-wire systems, but it can regulate the NPP. By analyzing the relationship between the NPP and 3-order harmonic, an optimal 3-order harmonic is determined. Using the optimal 3-order harmonic to calculate the switching angles for SHEPWM, the low frequency fluctuation of the NPP is suppressed obviously, which is important to improve the output performances and to reduce Dc-link capacitors. The simulation is done to verify the correctness and feasibility of proposed method.

    A pattern matching method for position sensorless control of IPMSMs having non-sinusoidal inductance spatial distribution in standstill and very low speed region has been proposed. In the proposed method, the rotor position is estimated by comparing the phase current derivatives measured in a real-time with those in advanced. The current derivatives are obtained by measuring the phase currents twice at the certain voltage vector of inverter switching. The certain voltage vector not only must be created in all rotor position, but also must continue for at least a minimum time (tmin) to measure the currents twice. However there exists conditions which could not be secured tmin depending on the load current and the rotor position. In previous researches, switching-state phase shift method is utilized in order to create the certain voltage vector by injection high frequency voltage in all rotor position. In this paper, proposed various switching-state phase shift methods are explained and strong and weak points of each method are compared. Furthermore, the effectiveness and remaining issues of each methods are represented by experimental results.

    A modeling approach for human action is the focus of this paper. We design a human action model based on the stored data obtained during long-term monitoring of a person. This approach consists of the following two processes. First, several kinds of partial time series data that occur frequently are extracted from the stored data and taken to be human action patterns. Next, the extracted time series data are modeled based on a statistical modeling method such as the hidden Markov model. In this research, we focus on the extraction method for the time series data that occur frequently in the stored data. A person changes his actions according to changes in the situation around him. Moreover, it takes some time for him to perform his action after he recognizes the situation around himself. This time is called the delay time in this paper. A human action model that takes this delay time into consideration leads to greater accuracy in recognition and prediction of human actions based on that action. It is necessary to extract time series data for a situation and an action with the delay time as training data in order to generate the above human action model. In conventional methods, multidimensional time series data are used as the stored data without a distinction between the situation and action data. Also, some partial time series data that occur frequently are extracted from the stored data. Therefore, the delay time is not taken into account. In this paper, we propose a new extraction method for time series data that occur frequently with the time delay taken into consideration. In this method, sets of partial time series data that occur frequently with the delay time are extracted by evaluating the repeatability and similarity between the partial time series data sets with different occurrence frequencies. In the experiment, we extract the interaction motions that occur frequently between two subjects. The utility of the proposed method is examined based on the experimental results.

    This study investigates compensation methods for harmonic components to realize PMSM position sensorless control in inverter overmodulation drive. While applying PMSMs as traction motor motors in an EV or HEV, operating PMSM in inverter overmodulation drive is an effective method to widen high-speed drive region of PMSM and achieve fast torque response when voltage saturates because it enable to utilize 27% higher fundamental voltage as compared to linear drive. In addition, position sensorless control is regarded as an important technique for adding a fail-safe function and downsizing of the drive system. However, the harmonic components which are inevitably generated in inverter overmodulation drive have negative effects on closed current control and position estimation systems. The key to realize position sensorless control in inverter overmodulation drive is an appropriate compensation for the harmonic components in the input voltage and input current of a the position estimator. There are several methods to achieve this, and differences in position estimation performance possibly exist among these methods. In this study, the compensation methods for harmonic components in overmodulation drive are compared, and a suitable compensation method for sensorless control is investigated through an experiment.

  1. Design of search space for improving the steady current control performance of PMSM current control system based on model predictive control

    This paper proposes a method to design the search space of Model Predictive Control (MPC) for improving the steady current control performance of Permanent Magnet Synchronous Motor (PMSM) current control system. A current control system based on MPC predicts the future current behaviors for considerable input voltage and determines the optimum input voltage by evaluating these behaviors. However, the basic MPC has inferior steady current control performance depending on the operating points. This is because the search space of basic MPC represented by voltage vectors is not suitable appropriate for PMSM current control. To overcome this problem, we consider difference of search space of basic MPC and current vector control with a modulator such as Pulse Width Modulation (PWM) or Space Vector Modulation (SVM) and clarify the necessary search space for improving the steady current control performance. Then, we propose a design method for the search space, and through experimentation, we show that proposed design method can improve the steady current control performance.

    With an increase in the elderly population, traffic accidents caused by elderly drivers have become an important social issue in Japan. The primary factor of traffic accidents by elderly drivers is a reduction in their driving skill. Therefore, elderly drivers are required by law to conduct regularly a driving aptitude test in Japan. If the driving skill of the driver is inadequacy, he is subject to punishment, such as driver license revoked. However, there is not appropriate evaluation index of driving skill. We have proposed a modeling method of driving behavior to support one. Proposed driving behavior model is generated based on the actual driving data of driver, and the generated model has some kind of habit and pattern of the driver. Therefore, it is considered that it is possible to evaluate driving skill of a driver by analyzing the generated model. According this reason, we aim to propose a modeling method of driving behavior to evaluate driving skill. Here, a coincident timing skill of driver is focused as a driving skill. In the case of driving behavior, the execution timing of driving operations is decided based on the prediction of subsequent change of the outside environment information. The accuracy of this decided execution timing of operation depend on the above prediction is called as the coincident timing skill. In the proposed model, the causality between the situation around a person and operation of driver is modeled by Hidden Markov Model, and timing probability distribution is added to Hidden Markov Model in order to evaluate this coincident timing skill. The timing probability distribution expresses the execution timing of next operation of driver. Therefore, it is possible to detect the information of the coincident timing skill of driver from the timing probability distribution. In the experiment, the controller operation of a radio controlled vehicle is modeled by the proposed method, and the usefulness of the proposed model is examined through some experimental results.

  3. Position Sensorless Control for IPMSM of Spatial Inductance Distribution with Nonsinusoidal Inductance Waveform Based on Pattern Matching Method Reviewed

    This paper presents a novel pattern matching based position sensorless control method for IPMSMs. A target IPMSM for the proposed method is designed such that it has high power and torque density, while also being significantly influenced by magnetic saturation. As previously reported in papers , for IPMSMs, heavy magnetic saturation affects the spatial distribution of phase inductances according to rotor positions. Most position sensorless controls at low speeds typically depend on the assumption that phase inductances have sinusoidal spatial distribution according to rotor positions. Therefore, it is difficult to apply conventional methods to IPMSMs with heavy magnetic saturation. In the proposed method, rotor position is estimated by pattern matching using feature values, so that the phase inductances have unique and reproducible value according to rotor positions. While template data sets are required for the proposed method, the assumption for sinusoidal phase inductances is not. In this paper, the effect of magnetic saturation for position estimation based on conventional methods is discussed in Section 1 and 2. Then, details of the proposed method are shown in Section 3. In Section 4, results of experiments carried out in steady state and transient state are presented. The effectiveness of the proposed method is verified through the experiments.

    This paper shows the effectiveness for employing the GaN-FET inverter for operating the traction motor of a compact Electric Vehicle. Utilizing GaN-FET inverter can not only reduce the conduction loss, but also reduce the switching loss. Therefore GaN-FET inverter can operate motors in higher switching frequency compared with Si-IGBT inverters. It is effective to increase the switching frequency of the inverter to improve the motor efficiency because harmonic iron losses can be reduced dramatically by increasing the switching frequency, but the inverter loss becomes relatively large when the switching frequency is set too high. Therefore, optimized switching frequency should be obtained to maximize the total efficiency of the motor drive system. Experiments are carried out to compare efficiencies of motor drive system with Si-IGBT/GaN-FET inverter in several switching frequencies. Optimization of the switching frequency for maximizing the total efficiency is demonstrated to make effective use of the GaN-FET inverter in the motor drive system.

    For single phase three level neutral point clamped (TL-NPC) rectifier, if the two DC-link capacitors are linked to two different loads respectively or a TL-NPC inverter, the neutral point potential (NPP) problem would be serious. It is rarely discussed at present, although some NPP control methods based on zero-sequence voltage injection have been raised, which does not deal with the asymmetrical loads in DC-side. Actually, if one phase voltage reaches to the maximum, the other one will go to the minimum. At this operation condition, the NPP control ability is limited, since there are few zero sequence voltage to choose. In this paper, a robust NPP control based on multiple degree of freedom (DOF) is proposed. Not only the zero sequence voltage, another two DOF are defined and utilized to control the NPP. As a result, the NPP control ability can be remarkably enhanced to deal with the NPP problem under some strong asymmetrical loads. The comparisons on the control domain of neutral point current for the traditional NPP control and proposed way are done firstly. Then, the simulation results are also given to verify the correctness and feasibility of proposed method.

    This paper aims to propose a new traction motor control system for electric vehicles (EVs). EVs are required to have higher energy efficiency in motor control systems for cruising longer distance. However, motor control systems, which are generally equipped with Si-IGBT inverters, have limits of the energy efficiency. Therefore, new inverters, which use wide bandgap (WBG) semiconductor devices such as Gallium Nitride (GaN), are expected to be a solution to improve the energy efficiency. Having less energy loss in conducting and switching operation than Si-IGBT inverters, the GaN inverters can increase the switching frequency. In addition, the reduction of harmonic loss of the motors will enable us to improve the energy efficiencies of the entire motor control system. Although previous researches have demonstrated the performance of various inverters, the experiments demonstrated only inverters of small capacities that are insufficient to be applied in traction motor control of EVs. Then, our research group are challenging to increase the power of GaN inverters and to realize their practical application to compact EVs. In this research, the switching frequency of the GaN inverter was dynamically changed to verify the higher energy efficiency of the motor control system. The results of the experiment have shown that the total energy efficiency can be improved by up to about 1.5% and the total loss can be reduced by up to about 10%.

    A novel decoupling control scheme of a Dual Three Phase (DTP) Permanent Magnet Synchronous Motor (PMSM) drive with two microprocessors applying current observer is proposed in this work. Multiphase drives are considered as a viable solution for safety-critical applications, and substantial works have been conducted for this purpose. However, it should be noted that for a fault-tolerant drive, not only the machine itself should be considered, but also control executed Microcontroller Unit (MCU) Therefore, a novel configuration of an integrated fault tolerant DTP drive with two independent MCUs has become the interest of this paper. Magnetic coupling between winding sets is a big issue causing instability and dynamic deterioration. In order to implement decoupling current vector control on this particular system, an observer that estimates the other subsystem output current is proposed and utilized. Effectiveness of the proposed drive has been verified by experimental results.

    In this paper, we propose a new system for operator support in teleoperation using Augmented Reality(AR) based on sensing data. In the proposed system, an 360-degree camera is equipped with a mobile machine in a remote place which is controlled by an operator, and the captured 360-degree image is displayed to the head mounted display put on the head of the operator. The operator can control the machine smoothly by watching what he needs for his current task by turning his head. In addition, the provided image around the machine has no blind spot because of the 360-degree image. However, a large transfer delay or a dropped frame occurs due to the enormous data size of the 360-degree image, which adversely influences the operator performance. In order to solve this problem, the AR image is actually provided to the operator, in which CG objects generated based on other sensor information are superimposed on the 360-degree image as AR objects. In this paper, the usefulness of the proposed method is shown through the experimental results on obstacle avoidance of a mobile robot by teleoperation.

    This paper aims to propose a control method of a high efficiency electric vehicles(EVs) drive motor and to verify its effectiveness. One of the ways to extend the driving distance is to improve the efficiency of the motor control system. However, existing motor control systems which use Si-IGBT inverters have limitations in terms of efficiency due to device restrictions. New inverters using wide bandgap (WBG) semiconductors such as Gallium Nitride (GaN) are being investigated to improve the efficiency. The advantages of a GaN inverter are the lower conduction and switching losses than a Si-IGBT inverter and the higher switching frequency. If the switching frequency is increased, the motor harmonic loss as well as the whole loss in the motor control system can be reduced. However, most of the existing research have focused on small capacity modules, which are not sufficient to study the motor control system of EVs. Therefore, our research group has been working on improving the GaN inverter to realize a compact EV. We are investigating variable carrier frequency control as a control method to make WBG semiconductors more useful. In this paper, a variable carrier frequency control is applied to a motor control system using GaN and SiC inverters, and we discuss the usefulness of wide bandgap semiconductors for electric vehicles by measuring the loss in WLTC mode with the systems. The experimental results show that the application of variable carrier frequency control to the motor control system with SiC inverter reduces the loss in WLTC mode by up to about 6% compared to the conventional control method.
