Induction motor drive with inverter control, which can reduce the total weight of the system, has been introduced to the Shinkansen trains in order to achieve high speed transportation.The individual-motor-control type 953 train, which is a part of the STAR21 prototype Shinkansen for high speed experimental run, was used for measurement running, in which we observed wheel slip and adjusted re-adhesion control parameters at the speed of 200 to 300km/h. It was found that the slip detection within one percent speed difference from the reference, was possible by adopting sensitive detecting method. Quick torque reduction by sudden reduction of motor current was necessary for re-adhesion control, and one-second waiting time before re-applying current was also inevitable. For re-applying the current, an exponential curve with four-second time constant was proved to be effective.By these tests, high speed performance and re-adhesion characteristics improvement by adjusting control parameters were obtained. To the next step, for example creep control, which utilizes fine continuous slip, should be investigated in order to keep enough torque minimizing current reduction during re-adhesion control.

We have developed a Re-adhesion control algorithm of traction inverter without any Motor speed sensors. In this paper, we are focusing on anti-slip control performance of this system. The influence of speed estimation delay is considered and a method to improve the delay is shown. Acceleration performance of the proposed system is same level as the one of current drive systems using speed sensors.

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.
