模糊自适应PID控制器在集中供热系统中的应用

The application of fuzzy adaptive PID controller in central heating system

基于对集中供热系统进行的数学模型辨识,并对常规PID控制器进行了调整,加入了模糊自适应控制,采用模糊工具箱进行了仿真试验。结果表明,模糊自适应PID控制器较常规的PID控制器,具有更好的鲁棒性和自适应能力。在复杂的集中供热系统中,达到了令人满意的控制效果。

This paper firstly established a mathematical model of central heating system, on the basis of which the general PID controller was adjusted. The fuzzy adaptive control was joined, and simulation experiment was made with the fuzzy simulation toolbox. The simulation results show that the fuzzy adaptive PID control is better than the general PID control in robustness and self- adaptability, and achieved the satisfying effect in the complex central heating system.
