It is challenging for controlling the position of a pneumatic cylinder. Cosys’s initiative approach based on dual closed-loop Ideal ^TM is to bring a linear transducer’s signal back into PPCs.

The PPCs compare desired setting value with feedback from the linear transducer and then fill or exhaust the cylinder with air to ensure that position is achieved.Thanks to the Cosys's PPC functions in closed loop, when the cylinder moves every steps , the PPC changes its pressure on its side to compensate and allow the cylinder to move back to its position. We've seen the application like this in these fields
