Abstract :
This paper presents a design method proposed to design an active disturbance rejection control for the hydraulic AGC control system which has the characteristics of nonlinearity, time-varying and time-delay. A simplified dynamic model is established and used to analyze the dynamic performance. And the active disturbance rejection control are then designed to improve the dynamic performance and robustness. Simulation results indicate that the proposed method has strong adaptability to the system and has advantages of no overshoot, short adjusting time and strong anti-disturbance ability.
