摘　　要：为了提高交流伺服系统在实际应用场合中的控制精度和性能特性,提出了模糊自适应PID控制器。模糊自适应PID控制,将传统的PID控制和模糊控制结合起来,可以发挥两者的优势,得到更优良的控制性能。基于Matlab/Simulink平台搭建了系统的仿真模型,内环采用PI控制,外环采用模糊自适应PID控制,并对模糊自适应控制中的模糊隶属函数进行了优化。在仿真平台上进行了突加负载实验,仿真结果验证了这种方法的可行性,同时,也可以获得较好的性能。A fuzzy adaptive PID controller was proposed to improve the control precision and the performance of AC servo sys-tem in practical applications. This method combined the traditional PID control with fuzzy control, which could give full play to their advantages and got more excellent control performance. The simulation model of the system was based on Matlab/Simulink platform, in which the inner loop adopted PI control, the outer loop used the fuzzy adaptive PID controller, and the fuzzy member-ship functions in fuzzy control were optimized.A sudden load experiments was conducted. The simulation results verify the feasibili-ty, and it also can get good performance.
