This paper proposes a model predictive control (MPC) strategy for permanent magnet synchronous motor (PMSM) to suppress the common mode current(CMC) in PWM motor system. Firstly, the MPC for PMSMs is illustrated in detail, which includes the prediction model of PMSM, prediction algorithm and cost function. Then, the CMC suppression method is further proposed based on the analysis of CMC formation mechanism. Finally, comparative simulation results are presented to verify the effectiveness and superiority of proposed MPC method.
