永磁同步电机的滑模PI模糊逻辑控制
Fuzzy Logic Control by Combining SMC and PI for PMSM
摘要
Abstract
The advantage of proportional plus integral (PI)is the simple construction,easy to implement and superior in the steady-state condition,the drawback is the contradiction between the fast response and the overshoot,and the PI is vulnerable to the system parameter variations and any external disturbances.Sliding mode control (SMC) is better under transient conditions,but the existence of chattering limits its application in practical engineering.A way of combining SMC and PI which is used in the PMSM servo systerm was proposed,it can smooth transition by fuzzy logic,to the traditional fuzzy linear switching function,a nonlinear switched function was introduced and has a smoothly transition,it can satisfy the dynamic response,enhance robustness and can also solve the chattering problem.At last,the simulation and real experiment results show that the method is correct and practical.关键词
