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.
Then, we apply the proposed method to the actual electric multiple units, which is Series 205-5000. 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. Moreover, this paper proposes the evaluation method of re-adhesion control test results.
