Witryna14 kwi 2015 · The electropneumatic positioning system (EPPS) uses two proportional pressure regulators mounted on the pneumatic cylinder, one on either side of the cylinder piston. One side maintains a constant pressure using the first proportional pressure regulator (E/P valve), while the second E/P valve controls pressure on the … WitrynaManual loop tuning was part and parcel of the pneumatic control age, but is now largely a lost art. Without expert guidance, tuning a flow or pressure loop can cause unusually long times to reach a desired setpoint or excessive loop oscillations. Most digital controllers employ an autotuning algorithm to set the PID parameters.
