摘要
空调房间温度控制是一复杂的控制过程,传统的模糊或PID控制很难得到较好的控制效果,模糊控制和PID控制适当结合控制空调房间温度可使控制效果大大提高。本文建立了房间温度控制模型,介绍了模糊和PID控制并联结合方式并对各复合控制器进行了设计。对设计的变频空调控制系统进行了仿真,结合仿真图,从鲁棒性和稳定性方面分析了设计的各模糊和PID复合控制器控制效果。
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.
