Distributed fuel control system (2) and methods are disclosed. A distributed fuel control system (2) may comprise a controller (4), a fuel delivery system (6), and fuel delivery system sensors (8) and combustion sensors (10). The controller may output a control signal (5) in response to at least one of the fuel delivery system sensor (8) or the combustion sensors (10). In response, the fuel flow to an individual multiplex fuel delivery unit (25-1 to 25-n) may be controlled according to various methods. One such method includes determining a desired fuel pressure differential, directing a torque motor (15) to set a pressure regulator (14) to a position corresponding to the desired fuel pressure differential, determining a sensed fuel pressure differential, and adjusting the torque motor (15) in response to a difference between the sensed fuel pressure differential and the desired fuel pressure differential. |
