Abstract：In AC servo control system,the mathematical model of the controlled object is usually not easy to determine,even if deriving the model of the controlled object by a large number of mathematical operations,there are also problems of multivariable, strong coupling,nonlinear and so on,for example,d-q model of permanent magnet synchronous motor in rotating coordinate system. Using traditional PI control,AC servo control system is often overshoot,unstable and slow dynamic response. Aiming at this problem, in this paper,the fuzzy ada-ptive PI controller is designed based on the fuzzy logic theory and the classical PID control theory,it is used to control the speed loop of permanent magnet synchronous motor A-C servo control system.Simulation experiment with Matlab/Simulink,and compared with the control effect of the traditional PI controller and the critical proportion method PI controller. The ex?perimental results show that the control effect of the fuzzy PI controller is better.
