Research on Adaptive Robust Tracking Control for Electro-hydraulic Servo Position System
The control problem of electro- hydraulic servo position system with load disturbance and parameters uncertainty is considered. At first, linear mathematical model of the electro-hydraulic servo position system is established in state space equations, and these equations are transformed into H∞ performance criterion questions. By using robust control theory, robust state feedback controller of the electro-hydraulic servo position system is designed. Then, a MRAC (Model Reference Adaptive Control) system is designed for the inner closed-loop system which is composed of the electro-hydraulic servo position controlled plant and the robust controller. Simulations results show that the controller proposed is effective for restraining load disturbance and parameters uncertainty, and is very useful to enhance track precision, which makes the system having better dynamic performance.
