“…We have to maintain constant pressure in the chamber, which determines its movement (Wos and Dindorf, 2013 module is cooperating with inductive position measuring system of the slider separator (position control) or module when it is controlled by the voltage (pressure control). This card usually contains standard classical regulators P, PD or PID, a correction of nonlinearity, hysteresis restrictions distributor, steepness of the fall and rise of the control signal, zero offset adjustment (Blasiak et al, 2017).…”
