Re-adhesion control in asynchronous motor drives for an electric train by monitoring excessive angular momentum

Abstract

Suppression of slip and reduction of friction between the rail and the wheel are important in railway systems. This paper proposes a novel slip re-adhesion control based on monitoring the excessive torque and the excessive angular momentum for four-axle and two-truck model. The effectiveness of the proposed method has been confirmed by mathematical analysis. In addition, the excessive angular momentum compensation of the proposed method was evaluated using real-world train test data. Furthermore, the proposed method can estimate the disturbance torque from real-world train test data. © 2013 The Institute of Electrical Engineers of Japan.
