電動機速度センサを有さない鉄道車両駆動用空転再粘着制御の考察

—4台誘導電動機一括制御の場合—

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.
