Control Strategy of Heating System Based on Fuzzy Adaptive PID in Variable Theory Domain
Aiming at the problems of low precision and slow response of traditional heating system control strate-gy,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 fac-tor,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 do-main fuzzy adaptive PID controller can effectively improve the control precision and response speed of the heating system,and has better stability,robustness and adaptability.
