Short summary
An electro-hydraulic servo system has the characteristics of high control accuracy and fast response so it is widely used in industrial control fields. To address the external load and disturbance problems faced in actual engineering, a dual observer is used to acquire the state and disturbance values and to provide the sliding mode controller to control the system in real time. Comparative simulations are conducted to verify the impact of the control method on the control accuracy.
