Abstract

This paper studies the problem of loading torque control for passive electro-hydraulic servo loading system with the external disturbance and parameter uncertainties. The state space model is established based on the nonlinear mathematical model of the system. Based on backstepping technique, an adaptive sliding mode backstepping control method is proposed for the system. By defining the sliding manifold and selecting a proper Lyapunov function, the final design of adaptive backstepping sliding mode controller is conducted and the stability of the controller is testified by the Lyapunov stability theory. The function of the controller was analyzed by comparative simulation study, which proves the feasibility and effectiveness of the proposed control strategy.
