Abstract
This paper focuses on the ability of application of electro pneumatic position control system based on. double acting pneumatic cylinder actuating by directional control solenoids valves and linked with position sensor. The suggested approach involved practical and theoretical work to realize an efficient pneumatic control system employed conventional solenoid valves instead of proportional or servo valves. It has required to set up a test rig contains the recommended electrical and pneumatic apparatus and involved the mathematical calculations as well as the computer simulation. A compare between practical and theoretical results have been carrying out to investigate the rendering of the suggested position control system including the position sensor. The obtained results showed that it can be used the directional control solenoid valve instead of other types of pneumatic valves such as proportional or servo solenoid valves with acceptable response and achieved position control system with high accuracy.
