In order to solve the problems of the complicated control system, based on the original PID control, by combining PID with fuzzy adaptive control algorithm, a fuzzy selftuning PID controller is designed. Then, a simula tion is carried out with the help of Simulink in MATLAB. The result shows that the fuzzy selftuning PID controller whose control effect is superior to the original PID controller has great adaptive capacity.%针对复杂系统的控制问题,在原有PID控制的基础上,将PID与模糊控制相结合,设计一种自整定模糊PID控制器,利用MATLAB中的Simulink软件进行仿真。仿真研究表明,自整定模糊PID控制器具有较强的自整定能力,控制效果优于原有PID控制器。
