空調(diào)房間溫度控制是一復雜的控制過程，傳統(tǒng)的模糊或PID 控制很難得到較好的控制效果，模糊控制和PID 控制適當結(jié)合控制空調(diào)房間溫度可使控制效果大大提高。本文建立了房間溫度控制模型，介紹了模糊和PID 控制并聯(lián)結(jié)合方式并對各復合控制器進行了設計。對設計的變頻空調(diào)控制系統(tǒng)進行了仿真，結(jié)合仿真圖，從魯棒性和穩(wěn)定性方面分析了設計的各模糊和PID 復合控制器控制效果。

Abstract: The control process of room temperature is complicated and it is difficult for traditional fuzzy control or PID control to get good control performance. In order to overcome the shortcoming of conventional controller, the fuzzy-PID composite control method is proposed. Fuzzy and PID control proper combine may get better controlling performance than signal controlling strategy. The mathematical model of the controlled plant is build and the controller based on fuzzy-PID is designed. Through simulating to three control models, the control performance of every controller may be gained and the composite control performance of every control model is analyzed in dynamic character and stability.
