Real-time distribution control of torque reference of commuter train for fine re-adhesion contol

The improvement of adhesion characteristics is important in commuter train. 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 actual commuter train composed of electric multiple units, which is Series 205-5000 of East Japan Railway Company. The proposed method drives the actual commuter train with high adhesion force utilization ratio. This previously proposed method considers the re-adhesion control performance for only each electric motor coach. Hence, it does not consider the total re-adhesion control performance for commuter train composed of electric multiple units. In order to keep the desired driving force performance, this paper proposes a new real-time distribution control of torque reference of commuter train composed of electric multiple units for fine total re-adhesion control performance.
