Design of Electro-Hydraulic Servo Force Feedback System Based on the GPC with Simplified Model

Abstract

An electro-hydraulic servo force feedback system is disturbed by a band-limited white noise, it adopted the conventional PID control algorithm. Simulated its dynamic characteristics. Constructed the system simplified model, Designed the GPC Controller and summarized its design procedure. The simulation based on the GPC with simplified model has been done. Compared the two simulation results, The GPC controller is more suitable when the system is disturbed by serious noise interference, It had been validated in project. This research have proved that design the electro-hydraulic system and choose the control algorithm can be proceed simultaneously, The efficiency and accuracy of the electro-hydraulic servo system design can be improved.
