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 Matlab / Simulink, the AHU control system which is commonly used in central air conditioning is simulated. A fuzzy self-tuning fuzzy-PID controller is designed and compared with the traditional PID controller. It is pointed out that the fuzzy PID controller has the advantages of high control accuracy and small overshoot, and has good performance on the change of object parameters Adaptability and robustness, suitable for air conditioning temperature control system with nonlinear, time-varying and time lag.
