Multi-permanent magnet synchronous motors (PMSMs) traction represents the future trend for driving high power traction equipment. Instead of the existing multi-PMSMs coordination control methods that are used to ensure the synchronization of a certain variable like position or/and speed, the purpose of this work is to achieve a consistent total traction torque of multi-PMSMs based on the actual requirement. Amulti-PMSMs coordination control model is developed to reduce the influence of traction torque fluctuation, and the direct torque control strategy based on sliding mode variable structure for each PMSM was constructed to improve its dynamic response performance. The simulation results under two cases are given to verify the effectiveness and feasibility
