摘　　要：传统PI控制器基于线性系统设计且参数固定,不能满足高性能控制的要求。而模糊控制不依赖于控制对象的数学模型,能够根据模糊信息实行精确控制。为了结合PI控制和模糊控制的优点,设计了一种模糊自适应PI控制器,并应用到永磁同步电机矢量控制调速系统中。该控制器能根据外部和内部参数的变化自动调节PI控制器的参数。仿真结果验证了,采用模糊自适应PI控制器的永磁同步电机矢量控制调速系统具有更好的动态和鲁棒性能。Conventional PI controller is designed based on linear system and its parameters are fixed,it is not able to meet the requirements of high performance.Fuzzy control doesn’t depend on the mathematical model of control system,and can control it accurately with fuzzy information.In order to combine PI control with fuzzy control,a fuzzy self-adapting PI controller was designed,and was employed in the speed regulating system of permanent magnet synchronous machine based on vector control.According to changes of outer circumstance and inner parameters,the fuzzy self-adapting PI controller is able to regulate the parameters of its embedded PI controller.Results verify that the speed regulating system of permanent magnet synchronous machine adopting the fuzzy self-adapting PI controller has better performance of dynamic and robustness.
