Abstract :
In view of the characteristics of nonlinearity, time-varying and time-delay in hydraulic AGC control system, a Smith fuzzy-PID complex control strategy is proposed. Smith predictor algorithm is used to compensate for the time delay and fuzzy control is used to enhance the robustness of the system, and then PID algorithms are used to improve the static precision of the system. The simulation results indicate that the method has characteristics of small overshoot, short adjusting time and strong anti-interference ability and robustness. It can further improve the quality of the strip thickness.
