Abstract

Abstract: Aiming at the problems of low stability, low loading precision and slow response of the servo hydraulic load simulator, a control method based on the combination of the optimal quadratic theory and the improved feedforward compensation is proposed. This method is based on the optimal quadratic theory to design the optimal control algorithm to optimize the structural characteristics. The hydraulic cylinder piston displacement signals are used as the input of feedforward compensation control to design improved feedforward compensation controller. The simulation results show that this control method can not only improve the dynamic performance of the aircraft rudder electro-hydraulic load simulator, but also can effectively eliminate the interference.
