The hydraulic/pneumatic pressure products are applied widely in current industrial area such as in the automation of products assembly, automation of equipment assembly, high-tech machine tool, aircraft, and train, and as the industry development is on progress, the development of the hydraulic/pneumatic pressure products is necessary and it is required in every industrial area. This research developed a position control system of the pneumatic cylinder using a pneumatic cylinder, four two-port valves, two three-port valves, two pressure valve, a check valve, two proximity sensors, and a program logic controller (PLC) to minimize the allowable error on the position control of pneumatic cylinder system and to develop a pneumatic cylinder valve system for further study. The maximum air pressure used for the position control test was 5 ㎏/cm2 and the displacement accuracy of the pneumatic cylinder was measured using a dial gauge. The supply and discharge air pressure and the length of the stroke of the pneumatic cylinder were controlled and set before experiment. The test of the position control of the pneumatic cylinder was carried out 50 times and replicated three times at each condition of the supply and discharge air pressure (2.5/3.5, 3.0/4.0, 3.5/4.5, and 4.0/5.0 ㎏/cm2) and selected stroke length of the pneumatic cylinder. The accuracy of the position control of the pneumatic cylinder increased as the supply and discharge air pressure increased at the stroke length was fixed as 133 ㎜, and increased as the stroke length increased with the fixed supply and discharge air pressure of 3.5/4.5 ㎏/cm2 of the pneumatic cylinder. The most accurate position control of the pneumatic cylinder (i.e., standard deviation of 0.01 ㎜) was obtained at the supply and discharge air pressure of 4.0/5.0 ㎏/cm2 and the stroke length of 170 and 190 ㎜.
