摘　　要：针对传统供热系统控制策略存在精度不高和响应速度慢的问题,提出了一种基于变论域模糊自适应PID的控制策略。设计变论域模糊自适应PID控制器,通过伸缩因子动态调整控制参数,根据系统状态调整模糊控制器的论域,从而优化控制效果和提高系统的整体性能。利用MATLAB建立仿真模型,与PID和Fuzzy自适应PID控制进行对比分析。结果表明,变论域模糊自适应PID控制器可以有效地提高供热系统的控制精度和响应速度,具有更好的稳定性、鲁棒性和适应性。Aiming at the problems of low precision and slow response of traditional heating system control strategy,a control strategy based on fuzzy adaptive PID in variable theory domain is proposed.The fuzzy adaptive PID controller with variable theory domain is designed,the control parameters are dynamically adjusted by stretch factor,and the theory domain of the fuzzy controller is adjusted according to the state of the system,so as to optimize the control effect and improve the overall performance of the system.The simulation model is established by MATLAB and compared with PID and Fuzzy adaptive PID control.The results show that the variable theory domain fuzzy adaptive PID controller can effectively improve the control precision and response speed of the heating system,and has better stability,robustness and adaptability.
