This paper presents an improved reaching law, and a sliding mode speed controller, based on the improved reaching law and grey prediction compensator, is presented for an Electro-Hydraulic Velocity Servo System. The proposed control strategy can forecast and reject the disturbances and parameter variations. This system has a fast response and a good disturbance rejection capability. The numerical simulation is presented to verify the effectiveness of the proposed control scheme. It is shown from the experimental results that the proposed controller offers several advantages such as fast response, good disturbance rejection capability, good velocity tracking capability and so forth. It is also revealed from simulation results that the proposed control strategy is valid for the Electro-Hydraulic Velocity Servo System.
