Utilizing Electro-Hydraulic Actuators in Motion Control System

Abstract

The motion control system with linear movement can be achieved by using several technologies. One of the most commonly used technologies in easy industry is the electro-hydraulic actuators. This is because of their handling rapid motion, high positioning accuracy, and thus producing large forces needed by equipment. The main objective of this work is to provide an electro-hydraulic system which depends on hydraulic actuators to meet motion control system demands. This is achieved by using solenoid directional control valves as well as a double acting single-ended hydraulic cylinder with limiting position electrical switches. Several control system architectures can be used where directional solenoid valve provide the economical option for the application. One electric voltage signal is required for actuating each solenoid while the electro-mechanical limit switches stop the rod of hydraulic cylinder in the set point. The process is carried out using a Matlab/Simulink to simulate hydraulic sub-system .The results show the ability to demonstrate hydraulic circuit containing solenoids directional control valves to control the motion of the rod for the hydraulic cylinder.
