Induction motor drive with PWM inverter control, which can reduce the weight of the driving devices, is used for Shinkansen trains in order to achieve high speed transportation.This paper describes the experimental results for controlling wheel slip and re-adhesion at high speed running with the type 953 Shinkansen test train. The induction motor for each axle of this train is individually controlled by an independent PWM inverter. By introducing the vector control for the induction motor drive system, quick response for the motor torque can be achieved when wheels are going to slip. The control scheme for the wheel slip and re-adhesion is that the motor torque is gradually reduced by increasing of wheel slip speed.The results show, it is possible to recover to adhesive condition against wheel slip, without excessive motor torque reduction, when the reducing torque value and control time constant are properly selected.By these tests, re-adhesion characteristics improvement by induction motor vector control are obtained. To the next step, the parallel motor control system with a vector controlled inverter will be investigated.

This paper presents a new vector control for induction motor drives in full block mode, so called One-Pulse mode, of inverters. For traction drives the inverter usually operates in this mode in a high speed region. The amplitude of voltage vector is restricted constant in the mode. The conventional vector control is not applicable as it requires controllability of both the amplitude and the phase of the voltage vector for all time. The proposed scheme provides quick torque response even in the One-Pulse mode. Experimental results are shown to validate the effectiveness of the control.

We have been studying the aplication of permanent magnet synchronous motor (PMSM) for railway vehicle traction in order to reduce the weight and size of direct drive traction motor. As a part of this study establishing a current control system of PMSM suitable for railway vehicle traction should be investigated.In this paper we discuss about designing method of current control system mentioned above and suggest a method which is available under the condition of railway vehicle traction, low switching frequency and long digital calculating period. Next we investigate how to decide current response time constant Td and reach a conclusion that it is about 10ms is appropriate under some assumed condition. Then we checked this current control system for railway vehicle traction through experiments and studies of influence of parameter changing. Consequently we can recognize the current control system has satisfactory performance for railway vehicle traction.
