Description
Summary:In general, an advanced control strategy is necessary for electro-hydraulic servo system to obtain fast and accurate system response. A novel control scheme called PID sliding mode control was proposed by combining conventional sliding mode control and PID control strategy. The linear dynamic mode of electro-hydraulic servo system was established precisely. The PID sliding mode control law was deduced in detail. The chattering problem caused by original sliding mode control was weakened by a continuous PID algorithm. The simulation results of electro-hydraulic servo system demonstrated the effectiveness of the proposed method.
