Electronic Fuel Control System Abstract Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP by a hydromechanical section. The hydromechanical section includes a torque motor which may be activated to modify the fuel flow to the engine in response to a control signal produced by an electronic control section. The electronic control section senses a number of engine and ambient parameters and generates engine operating limits from these parameters. The limit corresponding to the lowest maximum engine speed is selected and referenced to actual engine speed for generating the control signal, thereby providing a closed loop engine speed control. At least one of the computed limits is an actual maximum engine speed for steady state engine operation and is used to recompute the engine scheduled speed so that the actual maximum engine speed is obtained at the maximum power lever advance position; in this way power lever dead band is eliminated. The electronic control also modifies fuel flow to the engine for speed synchronization with another identically con- trolled engine.
