摘　　要：为提高永磁同步电动机控制系统的抗扰性能,设计了一种新型的模糊PI控制器.该控制器包括模糊控制器和PI控制器,采用模糊开关选择器根据系统的状态实现不同控制器之间的切换,实现简单.将该新型控制器用于永磁同步电机控制系统中,仿真结果表明:与传统PI控制永磁同步电机伺服系统相比,永磁同步电机模糊PI控制系统鲁棒性强、响应快、对被控对象参数变化具有较好的适应能力.A novel fuzzy PI controller is proposed to improve the disturbance - resisting performance of permanent magnet synchronous motor servo systems. This controller combines a fuzzy controller and pi controller to show their advantages at different stages. A fuzzy switch is designed to choose the main controller according to the states of system. This controller is adopted in a servo system of PMSM. The simulation results show that when compared to the traditional PI control system, system with the proposed controller is characterized by performances of good robustness to disturbances and parameter varieties ,quick response and better stability.
