Anti-slip re-adhesion control based on speed sensor-less vector control and disturbance observer for electric multiple units, series 205-5000 of East Japan Railway Company

The improvement of adhesion characteristics is important in electric motor coach. We have already proposed the anti-slip/skid re-adhesion control system based on disturbance observer and sensor-less vector control. The effectiveness of the proposed method has been confirmed by the experiment and the numerical simulation using the tested bogie system of electric motor coach. In this paper, we apply the proposed method to the actual electric multiple units, which is Series 205-5000 of East Japan Railway Company. In the experimental results of Series 205-5000, this paper discusses that the proposed anti-slip/skid re-adhesion control system has the desired driving wheel torque response and the desired anti-slip control performance.
