In order to solve the problems of heavy computational burden and large current pulsation in traditional model predictive current control of permanent magnet synchronous motor, a low-complexity dual-vector predictive current control method is proposed. First, the first voltage vector of the next cycle is obtained quickly by using the current beat control principle, which can reduce the number of prediction times of one cycle compared with the traditional method. Secondly, non-zero voltage vector can be used in the selection of the second voltage vector to increase the coverage of the alternative voltage vector. Finally, according to the root mean square current pulsation equation, the optimal acting time of each voltage vector under the condition of minimum current pulsation is determined. The simulation and experimental results show that compared with the traditional single-vector and dual-vector predictive current control, the proposed low-complexity dual-vector predictive current control method can effectively suppress the current pulsation, reduce the complexity and computation of the algorithm, and improve the performance of the permanent magnet synchronous motor control system in practice.
