Patent number: 8831792Abstract: A method and system for controlling a pressure regulator in a gas storage system using a pressure switch as a pressure measurement device. A controller uses supply pressure data and gas flow demand data to compute a feed-forward control term, and uses data from a pressure sensor downstream of the pressure regulator to compute a feedback control term. During normal operation, with pressure downstream of the regulator oscillating about a set point pressure, on-time and off-time periods of a pressure switch are monitored, and an adaptive control term is computed which balances on-time and off-time. If the pressure sensor fails, excessive switch on-time or off-time will be detected; in response to this, the feedback control term is disregarded, and an adaptive control term is computed which aims to restore balanced on-time and off-time of the switch, thus indicating that the actual pressure is oscillating about the set point.Type: GrantFiled: June 28, 2011Date of Patent: September 9, 2014Assignee: GM Global Technology Operations LLCInventors: Oliver Maier, Thomas Weispfenning

Patent number: 8634967Abstract: An electrohydraulic pressure control arrangement comprises a proportional pressure valve and a control loop structure. The control loop structure has a control path through which an actuating variable is fed to an actuating input of the proportional pressure valve starting from a setpoint pressure value.

A weighting element subjects the control error to a weighting operation and thus determines a weighted control error. The weighting element is designed such that relatively large control errors are attenuated to a greater extent than relatively small control errors.Type: GrantFiled: March 4, 2011Date of Patent: January 21, 2014Assignee: Robert Bosch GmbHInventors: Georg Schoppel, Roland Gerhart
