摘要：
A sliding mode back-stepping control method was proposed for the mismatched disturbances in valve-controlled electro-hydraulic position servo system. A new smooth and continuous sliding mode control law was applied to the design of sliding mode back-stepping control algorithm. The stability of the proposed control algorithm and the convergence of tracking error were theoretically and quantitatively analyzed. The feasibility and validity of the control method were verified by co-simulation. The results show that the algorithm can effectively suppress unknown mismatched disturbances and output chattering. Compared with back-stepping controller and PID controller, it has better tracking effect. © 2020, Central South University Press. All right reserved.
