Modeling and Simulation of Electro-Hydraulic Proportional Position Control System with the Flexible Hose

A method which utilizes the power bond graph to establish the flexible hose model is described in this work. By using this method, the paper establishes mathematical modeling for the location of electro-hydraulic proportional control system with the flexible hose. And then, this article completes dynamic simulation by MATLAB and analyses the results of simulation. The effect of the flexible hose parameters on dynamics characteristics of the hydraulic system is also studied.
