Abstract

In this paper, variable structure control (VSC) with reaching law is presented for an electro hydraulic position servo control system to achieve accurate servo tracking in the presence of load disturbance and plant parameter variation. The proposed control technique achieves a zero steady-state error for step input and has a good dynamic transient and no chattering in the control input. The performance of the controlled servo system has been evaluated through digital simulation by varying the inertia of the motor and the load disturbance
