Advanced anti-slip and anti-skid re-adhesion control considering air brake for electric train

The improvement of adhesion characteristics is important in electric commuter train. We have already proposed the anti-slip/skid re-adhesion control system based on disturbance observer and sensor-less vector control. Generally, the actual train uses both electric brake and air brake in the high-speed range. Then, this paper discuss on an anti-skid re-adhesion control system of electric train considering air brake by using the tangential force estimator based on disturbance observer. We apply the proposed method to the actual electric multiple units, which are series 205-5000. The experimental results using actual electric train point out that the proposed system has the desired anti-slip and anti-skid re-adhesion control performance
