Dynamic Sliding Mode Control Scheme for Electro-Hydraulic Position Servo System

摘要：

In order to solve the uncertainties in the position servo system, caused by servo system without modeling accurately, which may cause the deterioration of the control quality of the electro-hydraulic position servo system (EHPSS) and even lead to its instability, a dynamic sliding mode control strategy is proposed for an EHPSS.Based on dynamic switching function, the proposed control strategy has fast response and 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 position tracking capability and so forth.It is also revealed from simulation results that the proposed control strategy is valid for the EHPSS.
