To solve the problem of poor steady-state performance of the duty cycle model predictive current control (DC-MPCC) for permanent magnet synchronous motor (PMSM) and the problem of a large amount of calculation of the dual vector model predictive current control (DV-MPCC), the improved dual vector model predictive current control (IDV-MPCC) is proposed. All the voltage vectors are divided into two vector sets according to the error of all the candidate voltage vectors corresponding to the predictive current and the reference current, and one voltage vector is selected from each of the two vector sets for each control period. According to the simulation results, the steady-state performance of IDV-MPCC at low speed is similar to that of DC-MPCC and DV-MPCC. The q-axis current ripple and torque ripple of IDV-MPCC are obviously improved when the speed increases, and the amount of calculation decreases compared with DV-MPCC. On this basis, a control strategy is proposed to switch between DC-MPCC and IDV-MPCC according to the speed, which can maintain a good steady-state performance in a wide range of speed changes while reducing the amount of calculation at low speed.
