Abstract
Distributed fuel control system and methods are disclosed. A distributed fuel control system may comprise a controller, a fuel delivery system, and fuel delivery system sensors and combustion sensors. The controller may output a control signal in response to at least one of the fuel delivery system sensor or the combustion sensors. In response, the fuel flow to individual multiplex fuel delivery unit may be controlled according to various methods. One such method includes determining a desired fuel pressure differential, directing a torque motor to set a pressure regulator to a position corresponding to the desired fuel pressure differential, determining a sensed fuel pressure differential, and adjusting the torque motor in response to a difference between the sensed fuel pressure differential and the desired fuel pressure differential.
