Analysis of Hydraulic Press Servo System Based on Robust Controller

Abstract:

This paper researches and analyzes the modeling of electro-hydraulic proportional servo system to improve the characteristics of forging hydraulic servo control system and meet their requirements of forging a variety of materials. Based on robust compensator design, PID control strategy is proposed with uncertain disturbance of hydraulic press hydraulic servo system and the response characteristics of the system is simulated and analyzed. The results show that hydraulic press servo system which uses robust compensator has better performance than the traditional PID control and the chattering is eliminated. The test results and simulation results are compared by building simulation test system of 60MN hydraulic press electro-hydraulic proportional control system.
