一种模糊自适应控制器在室温控制中的应用

Application of a fuzzy self-adapting controller in control of roomtemperature

目前已广泛应用的新风机组空调系统,能满足对大多数室温的控制要求,但不能满足控制室内空间较大且干扰频繁的室温控制要求,针对这种情况应采用模糊自适应方法来调节室温。本文设计了直接自适应控制器,并用Matlab对该控制器的稳定性和鲁棒性进行仿真。仿真结果表明该模糊自适应控制器具有较好的鲁棒性、快速性和准确性的优点。

Fresh air conditioner system used extensively at present can meet the requirement of controlling room temperature, but it can't meet the requirement of controlling room temperature of larger indoor space and frequent disturbances. To solve this problem, a method of fuzzy self-adaptation should be used to control the room temperature. In this paper direct self-adaptation controller is designed and its stability and robust are simulated by Matlab. The result of simulation shows that the controller has advantages of better robust, faster response, and higher accuracy.
