(Summary) Characteristics and controllability analysis of the motor is tested by using the M-G set which is combining the motor and generator. The test of motor of tens of kW class that is used for the electric vehicle need the suitable generator or servo system. Thus, it is impossible to avoid the high cost and the increasing size of the M-G set. In this laboratory, we have conducted productions and experiments of the motor loading test equipment for the purpose of low speed, high torque test using auto parts. The equipment makes it possible to constant torque load test by feedback the hydraulic disc brake. It can more compact and inexpensive than with the servo system and the generator. In this paper, the loading test equipment was examined in consideration of not just the motor, but also chassis dynamo. As the results, it was confirmed that the constant speed test is possible in addition to the constant torque test. Therefore, we describe the diversity and ability test, report the experimental results include of the production process.

(Summary) The PM motor has become increasingly popular for many applications. We proposed a novel synchronizing signal sensor-less vector control method without using any machine model parameters to be able to drive any AC motors. The proposed system was able to be easily constructed without any motor parameters. So far, we proposed electric vehicles (EV) driven by induction motor and PM motor using the proposed sensor-less control method. Moreover we developed a prototype Hybrid Vehicle (HV) driven by an AC Synchronous Motor (SM) with a developed an inverter unit. The HV was converted from a general gasoline vehicle, which is MITSUBISHI LANCER Evolution -CN9A. The HV was reconstructed by an IMsynRM (15kW) and SPMSM(10kW), lead acid batteries (300V, 16Ah), and the handmade inverter units using IGBT devices (Generator unit 600V-400A, motor unit 600V-600A). Total weight of the HV is approximately 1,600kg. In this paper, we introduce the development process and features of the HV. Furthermore we report characteristics of IMsynRM that we developed.

(Summary) Permanentmagnet (PM) motors have become increasingly popular owing to their use in many applications. PM motor drives require rotorposition sensors. Many techniques that do not involve the use of sensors have been developed for estimation the rotor position from voltage and current measurements.We proposed a novel sensorless control system for PM motor drives that did not require position estimation(3). The system can be easily constructed without using any motor parameters. The system works well over a wide speed-control range; from low to high speeds.In this paper, we describe in detail the principle underlying the proposed sensorless control system for PM motor drives and demonstrate the implementation of the system. Further we present experimental results that confirm the feasibility of the proposed control system.

(Summary) 太陽光発電システムが多数台連系される際に，配電線電圧の上昇が懸念されている．この電圧上昇の対策の一つとして，太陽光発電システムの系統連系インバータの無効電力制御を行う方法が挙げられる．しかし，現在の系統連系インバータには外部制御信号を受けつけるような通信機能がなく，また力率には制約が設けられていて，無効電力制御の可能な範囲は限られている．これまで筆者らは，多数台の系統連系インバータを制御する方法として，準集中制御方式を検討し，新たな制御方法を提案した．これにより，柱上変圧器以下の電圧情報のみを用いて，負荷変動などにより電圧が適正範囲内に収まった場合には無効電力出力を止め，無効出力が十分の場合には出力量を緩めることが可能となった．本稿ではこれを用いて，一日を通しての負荷変動とPV発電出力を考慮し，1時間おきの各node電圧について検討した結果について述べる

(Summary) Awareness of vehicle safety technique not only structure of body also prevention from traffic accident in advance is growing. In recent years, the number of traffic accidents is decreasing by safety improvement of vehicle body. However there are quite a number of traffic accidents. Therefore active safety techniques which can prevent from accident in advance have attracted much attention and started to install. In the course of the development of the active safety needs a lot of experiments and creation of a complex algorithm. That's why the development is carried out by using a driving simulator although it requires a large space. In this paper, we propose a simplified driving simulator which can provide a realistic experience of driving to the driver by using a radio control car and electric actuators. This paper describes a development process of the simulator and operation results in experiments.
