系统中模糊自整定PID控制器模拟
Simulation of fuzzy self-tuning PID control in AHU system
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。

Abstract：
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.
