Anti-skid Re-adhesion Control Based on Disturbance Observer Considering Air Brake for Electric Commuter Train

摘要

This paper proposes a new anti-skid re-adhesion control based on disturbance observer considering the air brake for electric commuter train. We have already proposed the anti-skid re-adhesion control with regenerative braking system based on disturbance observer. This proposed method has been the re-adhesion control using only regenerative braking mode. However, actual train uses both electric brake and air brake in the high-speed range. Hence, this paper proposes a new anti-skid re-adhesion control considering the air brake, which carries out the cooperation control of electric brake and air brake in order to realize a fine re-adhesion control. The numerical simulation results point out that the proposed system has the desired driving wheel torque response and a fine anti-skid re-adhesion control.
