摘要
传统三相异步电机PI控制算法的参数固定不变，不能使控制系统一直处于最佳运行状态。针对此问题，在传统矢量控制系统中引入了模糊PI控制方法，利用模糊控制理论设计出一种新型模糊PI控制器，在Matlab／Simulink仿真软件中设计了模糊PI控制模型。通过仿真分析可知，模糊PI控制比传统PI控制能更快地建立起旋转磁场，且动态响应快，能实时抑制超调量，因此，模糊PI控制法更具有优越性。最后通过实验证明模糊PI控制方法能使系统获得更快的平缓转矩响应。
Because of the parameters of the traditional three-phase asynchronous motor PI control algorithm are fixed, which can not make the control system running at best all the time.Aiming at this problem, the traditional vector control system is designed in the Matlab/Simulink simulation software.Through simulation analysis fuzzy PI control method is better than the traditional PI control method,and it can quickly establish the rotating magnetic field.And fuzzy PI control method is better than the traditional PI control method of fast dynamic response, real-time restraining overshoot,therefore,fuzzy PI control method is better than the conventional control method has more advantages.Finally, experimental verification of the fuzzy PI control method is superior to the traditional PI control method, which can make the system have more smooth torque response.
