Position Control of a Pneumatic Cylinder Considering Friction Compensation. Most cylinders operate to two positions, extended and retracted. By installing position switches for each case, the control system can be configured to alarm if a cylinder has not reached the commanded position when expected. It is also possible to add more switches to indicate when actuators reach midway positions. directional control valve powers a double-acting cylinder in the vertical position with its rod up. For Your hardware configuration it will function at rather low frequencies (as relays and valves need some time to be open), but properly tuned it should give You satisfying results, reaching desired joint angle fast and with small regulation error.

Air cylinders will not hold position accurately, nor for very long, because of the volume differential caused by the shaft. Designed and manufactured in the USA, our pneumatic valves, fittings, manifolds, and custom pneumatic components are relied upon for fluid control throughout a wide variety of industries. 3/2-way means three ports and two positions: one port connects to the source of compressed air, one port is required as exhaust and the third port connects to the cylinder. Upon releasing the directional control valve to the at-rest position, air exhausting from the cylinder must pass through the variable restriction (flow control) and the retraction rate will be controlled. Pneumatic cylinder is a well-known device because of its high power to weight ratio, easy use, and environmental safety.
