摘要：

This brief investigates the displacement tracking control strategy of uncertain electro-hydraulic systems (EHS). Due to the existence of parametric uncertainty, a kind of sliding mode observer (SMO) is firstly introduced to EHS to estimate the parametric uncertainty. Based on this sliding mode observer, a novel kind of integral sliding mode tracking controller is designed to conquer the nonlinearity of EHS possesses and realize the high-precision displacement tracking control aim. The feasibility of proposed theoretical strategy is validated via simulation with the corresponding simulated results are provided.
