Torque tracking control of permanent magnet synchronous in-wheel motor for electric vehicle

Due to the strongly coupled characteristics of permanent magnet synchronous motors(PMSM), the feedback linearization method is presented to decouple the torque current and the flux current in the dynamic state, and control both currents respectively to achieve a quick and precise torque tracking control. Then, the effectiveness of the control method is validated by an effective simulation model of PMSM based on AMESim. Finally, the simulation results are analyzed and compared with PID control method. The simulation results show that the proposed method in this paper has better torque tracking performances.
