Abstract
An exemplary embodiment of the invention is directed to a fuel flow control system for use with a fuel distribution system having a plurality of zones each including a servovalve. The fuel flow control system includes a fluidic multiplexer having a plurality of pressure ports and a plurality of servoflow ports. The fluidic multiplexer sequentially receives pressure from each zone and sequentially provides servo fluid to each servovalve. A pressure sensor is fluidly coupled to the pressure ports and generates a pressure signal for each zone. A controller receives the pressure signal and generates a control signal. A driver receives the control signal and increases or decreases flow through the servoflow ports in response to the control signal.
