Motion control of electro-pneumatic system based on directional control solenoid valve

Abstract

This work is concerned with the design and implementation of position control electro-pneumatic system using ON/OFF solenoid directional control valves. To realize this approach, it's required to set up a laboratory mechanical test rig involving pneumatic, mechanical and electrical apparatus. The proposed design of control system includes electro-pneumatic circuit interfacing with position sensor, especially used in this work to detect the distance of the rod of pneumatic actuator. The suggested model mainly consists of double acting pneumatic cylinder, two solenoid directional valves, two position sensors and electrical control circuit. The simulation process of the employ system has been done with using MATLAB software and the obtained theoretical as well as practical results have been compared to investigate the pest performance. The obtained results showed that the proposed system can be applied with high accuracy and efficiency.
