Abstract Aiming at the problem of current loop control performance would be deteriorated when permanent magnet synchronous motor (PMSM) drive system operates under low carrier modulation ratio condition, the principle of single vector model predictive control (MPC) of PMSM is analyzed. In addition, the strategy of 3-vector model predictive control of PMSM is obtained. Furthermore, as the MPC is capable of considering the multiple control objectives and system constraints, it could improve the system performance when considering the converter switching frequency in the strategy. As a consequence, a 3-vector model predictive control with low switching frequency is proposed in this paper, which can effectively reduce the converter switching frequency and improve the static and dynamic performance of the current loop. Finally, the simulations and experiments are conducted to make a comparison based on a PMSM drive system between the traditional vector control and 3-vector MPC with reduced switching frequency. The results are used to verify the feasibility and correctness of the proposed control strategy, which show that the investigated method is superior to the traditional vector control strategy.
