Abstract:
1. A system for controlling a pressure regulator comprising: a pressure sensor for providing a measurement signal quantifying a pressure downstream of the pressure regulator; a pressure switch for providing an off signal that indicates that the pressure downstream of the pressure regulator is above a set point pressure, or an on signal that indicates that the pressure downstream of the pressure regulator is below the set point pressure; and a controller responsive to the measurement signal from the pressure sensor and the signals from the pressure switch, said controller being configured to use a combination of a feedback control term, a feed-forward control term and an adaptive control term to control the pressure regulator such that the pressure downstream of the pressure regulator seeks the set point pressure and such that on-time and off-time periods of the pressure switch are balanced.
