针对传统内模控制方法不能兼顾系统跟随性、抗干扰性和鲁棒性的问题,提出了一种基于三自由度内模控制的永磁同步电机矢量控制方法。该方法基于永磁同步电机矢量控制系统,分析了系统实现稳定性和鲁棒性的条件,根据永磁同步电机矢量控制系统的稳定性和鲁棒性条件设计了反馈控制器、反馈滤波器和前馈控制器,从而实现分别对永磁同步电机矢量控制系统的跟随性、抗干扰性和鲁棒性三种性能的优化控制,提升永磁同步电机的控制性能。仿真和实验结果验证了基于三自由度内模控制的永磁同步电机矢量控制方法的正确性和有效性。

A Vector Control Method Based on Three-Degree-of-Freedom Internal Model Control for Permanent Magnet Synchronous Motor

A vector control method based on three-degree-of-freedom internal model control (3DOF-IMC) for permanent magnet synchronous motor (PMSM) is proposed in this paper,to solve the problem that the traditional internal model control (IMC) method cannot tune the performances of tracking capability,disturbance rejection and robustness independently.The proposed method analyzes the stability and robustness based on the vector control system of PMSM.The 3DOF-IMC controllers contain feedback controller,feedback filter and feed forward controller,which are designed based on the analysis of the stability and robustness.This 3DOF-IMC method can tune the performances of tracking capability,disturbance rejection and robustness independently with its three controllers and improve the control performance of PMSM.The correctness and effectiveness of the proposed method are verified by the simulation and experiment results.
