Aiming at the problem that the traditional PID control method cannot meet the control accuracy requirements of the heating furnace,this study designs a heating furnace control system based on adaptive fuzzy PID.On the basis of the introduction of hardware and software,self-resistant(ADRC)control is introduced into the fuzzy PID controller to avoid the overshooting phenomenon of the system,and the fuzzy control system is used to adjust the key parameters of ADRC to form the adaptive fuzzy PID control technology to achieve the precise control of the heating furnace.The results show that the system control performance reaches the best when the integration step h and speed factor R are set to 0.005 and 5,respectively,and the control performance comparison results with other algorithms show that the adaptive fuzzy PID control algorithm can reach the stable state quickly without overshooting phenomenon,which has obvious application advantages.
