摘　　要：定风量空调系统的调节是通过调节冷冻水流量实现的,建立了各个部件的数学模型,通过调节水泵转速来调节冷冻水流量。由于空调系统参数的时变性,常规PID控制存在局限性,本文建立自适应模糊PID控制器,并与常规PID控制器进行比较,表明自适应模糊PID控制调节效果更好,简单易行。The control of air conditioning system of constant air volume is realized by adjusting the chilled water flow.This paper establishes the mathematical model of the parts by adjusting the pump speed to change the freezing water flow.Conventional PID control has limitations because of time-varying parameters.The adaptive fuzzy PID controller is adopted,which is better,simple and feasible compared with conventional PID controller.
