Vector Control of PMSM Based on Proportional Resonance Control

Permanent magnet synchronous motor (PMSM) has a wide range of applications. For its nonlinear and strong coupling characteristics, a vector control scheme for permanent magnet synchronous motor based on proportional resonance (PR) control is proposed. The mathematical model of permanent magnet synchronous motor is established. The principle of proportional resonance control is analyzed. The three-phase PMSM vector control system based on PR controller is designed and built with MATLAB simulation tool. Compared with the PI control in the traditional current closed-loop control, the simulation results show that the proposed method is relatively simple, improve the robustness of the control system, and meet the high-performance vector control of permanent magnet synchronous motor.
