摘要
本文针对温度对象的非线性、时变性和大滞后性等特点,将模糊控制技术与传统PID控制相结合,提出了一种分段的模糊自适应PID控制器的设计方法,并将其应用于中央空调系统的温度控制。Mtalab仿真结果表明,这种方法响应快、精度高,提高了系统的动、静态特性。
According to the characteristics of temperature：nonlinearity,time-varying and large delay,this article combines the fuzzy logic control and the conventional PID control. A design method of PID controller which is sectionalized and self-adaptive is presented,and adopted in the temperature control of central air-conditioning system. Matlab simulation shows that this method has fast response and high accuracy,and can improve the dynamic and static characteristics of the system.
