A Torque Command Generated Method of Re-adhesion Control Based on Slip Acceleration

This paper proposes a new method of generating torque command for re-adhesion control by analyzing the mechanical equations of electric motor and train. The method of torque command is based on designing the reference slip acceleration without requiring a lot running control parameters and running test, so that the slip acceleration of the train in slip/skid state is negative and the amount of slip velocity can be theoretically determined. The effectiveness of the proposed method has been confirmed by the numerical simulation with high utilization ratio of adhesion force.
