Evaluation and Discussion of Disturbance Observer Based Anti-Slip/Skid Re-Adhesion Control for Electric Train

Abstract

The improvement of adhesion characteristics is very important for electric train. The driving system of electric train is requested to have a fine anti-slip and anti-skid re-adhesion control system. In order to overcome this problem, we have already proposed anti-slip/skid re-adhesion control system based on disturbance observer and sensor-less vector control. Moreover, we have already applied the proposed method to the actual electric multiple units, which is Series 205-5000. In the experimental results of Series 205-5000 and the numerical simulation results, this paper evaluates and discusses that the proposed anti-slip/skid re-adhesion control system has the desired driving wheel torque response.
