Prof Department of Mechanical Engineering Maratha Mandal Engineering College, Belgaum,Karnataka, India Abstract: - The present work is conducted to study the performance of hydraulic control system and the designed of electro-hydraulic control circuit contained hydraulic directional control valve size type [4WRE6981X/24Z4M]. The theoretical part includes essential branches. The analysis of the system is used to find the mathematical model to the electro-hydraulic system and a nonlinear analysis for the system for three position spool to proportional directional control valve. The theoretical results of the control system were developed using the Matlab/SIMULINK to simulate the system and drawing the results as a step responses. This shows a steady response of the system to step inputs at different case studies Keywords: hydraulic directional control valve, mathematical model, Matlab/SIMULINK. I.INTRODUCTION The use of hydraulic systems for control and regulation has made possible important fields for automation. However, in spite of the specialized field has not yet been c
