摘　　要：以Matlab/Simulink为基础,对集中空调常用的AHU控制系统进行了仿真研究。设计了一种模糊自整定Fuzzy-PID控制器,并与传统的PID控制器进行了比较,指出模糊PID控制器具有控制精度高、超调量小的优点,对对象参数的变化具有很好的适应性和鲁棒性,适合在具有非线性、时变性和时间滞后性的空调温控系统中应用。Based on the Matlab/Simulink, simulates air handle units （AHU） commonly used in central air conditioning system, and develops a fuzzy self-tuning PID control system. By comparing fuzzy-PID control and conventional PID control, finds that the former control has higher precision, smaller overshoot, and the method has favorable adaptability, robustness and disturbance-rejection especially when the parameters of the object are changed, and can effectively control the air conditioning system which is nonlinear, frequently variable and time-delaying.
