| 摘 要： | 将模糊PID控制应用于变风量空调系统中，任务是将送风温度和空调房间内的温度（回风温度）控制在各自的设定目标值附近。分别设计了变风量空调系统的送风温度模糊PID控制系统和室内温度（视为回风温度）模糊PID控制系统，通过调节冷冻水阀门的开度来控制送风温度，通过调节变频风机的转速来控制室内温度。应用所设计的模糊PID控制器对送风温度和空调房间的温度（即回风温度）进行了实时在线控制，控制结果表明模糊PID控制器设计合理，控制效果良好。

| Abstract: | Fuzzy PID controller was applied in variable air volume system. The task was to control the temperature of supply air and the temperature of air conditioned room (the return air temperature) close to their respective targets. The fuzzy PID control system of supply air temperature and return air temperature was designed respectively. The supply air temperature was controlled through adjusting the valve opening of chilled water. And the indoor temperature was controlled through adjusting the rotational speed of variable frequency ventilator. The supply air temperature and the indoor temperature (return air temperature) were controlled online by fuzzy PID controller. Thus, it was shown that the design of fuzzy PID controller was reasonable and the effect of fuzzy PID control was well. |
