Pressure Pulsation System in Electro-Hydraulic Control Valve of Engineering Mechanical

摘要

In order to overcome steady-state error and low-velocity scrawl problems caused by friction in electro-hydraulic control system of engineering mechanical, method for overcoming nonlinear friction force of pressure pulsation system is adopted in this study. A new pressure pulsation system is proposed, mathematical model of the pressure pulsation system is established, based on the MATLAB fuzzy control strategy and simulation. The results show good dynamic performance of the system.
