基于灰色预测模糊PID算法的空调房间温度控制

针对中央空调系统房间温度控制系统的大惯性、纯滞后和时变性特点,设计了将等维新息灰色预测控制与模糊自整定PID相结合的新型控制器,建立中央空调房间温度控制系统的数学模型,介绍灰色预测模糊PID控制器结构,并对该控制方案进行了数字仿真。仿真结果表明,该控制器比PID控制器、模糊PID控制器有更多优越性,调节迅速,超调小,有更好的动、静态性能,具有一定的可行性。

Temperature of air-conditioning control based on grey predicative fuzzy PID control algorithm

According to the large time constant,long time-delay and time-varying characteristic of the control object of room temperature,a new fuzzy self-setting PID controller with grey prediction was designed.The mathematical model of the control plant was built,the structure and principle of grey predictive fuzzy PID controller were presented,and the simulation researches were carried out,the result shows that,compared with PID controller and fuzzy PID controller,the controller has characteristic of rapid adjustment with small overshoot and better dynamic and static performance.
