A controller design for electrohydraulic position servo control system

The paper is concerned with the design of a tracking controller for controlling electrohydraulic position servo systems based on a deterministic approach. The system is treated as an uncertain system with bounded uncertainties where the bounds are assumed known. It is shown that the electrohydraulic position servo system with the proposed controller is practically stable and tracks the desired position in spite of the uncertainties and nonlinearities present in the system.
