Application of fuzzy-PID in control of FC furnace gypsum calcination temperature

Conventional PID control algorithm is difficult to obtain good effect in control of the temperature of FC furnace gypsum calcination which is characterized by time-varying process, nonlinearity, and big disturbance. In view of the steady-state accuracy of PID control, strong robustness and fast response of fuzzy control, this paper designs fuzzy PID controller to control the pre-drying temperature by overcoming disturbances in the system through online adjustment of the PID parameters. Simulation results show that this control strategy has high-speed quality and stability compared to conventional PID.
