ABSTRACT:
A valve assembly controls a pressure sent from a valve to create a pilot signal used to control a mechanical booster regulator. An independent feedback line extends from both the output of the valve and the output of the mechanical booster regulator wherein the outputs are scaled after a transducer in each feedback line converts the information received from the pressures into voltages. The difference in the voltage is integrated and added to the input command signal which dictates the parameters of the mechanical booster regulator operation. The voltage feedback from the pilot pressure is then subtracted from the modified command signal. The feedback signals approach a negligible correction as the mechanical booster regulator approaches the designed output pressure because the integration is eliminated and the pressures cancel each other as the system approaches a static condition.
