Abstract

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.
