  • Actuator flow compensated direct metering fuel control system and method
    Patent number: 8291886
    Abstract: A system and method for controlling the fuel flow rate in a direct metering fuel control system to compensate for actuator flow. The system includes a fuel metering pump that supplies fuel to a fluid-operated actuator and to a gas turbine engine combustor and determines, using a generated model of the fuel metering pump and/or the fluid-operated actuator, fuel flow rate needed by the gas turbine engine and/or the actuator fuel flow rate needed by the fluid-operated actuator. The fuel flow rate of the fuel metering pump is controlled based on the determined actuator fuel flow rate and the determined engine fuel flow rate.

  • Feedback control system and method that selectively utilizes observer estimates
    Patent number: 7630820
    Abstract: A system and method implements improved machine performance, most preferably for gas turbine engines. The system and method implement a control law that receives sensed operational parameter feedback signals. For each sensed engine operational parameter, the feedback signals that are supplied to the control law selectively comprise the sensor signal representative of the engine operational parameter, if the sensor signal is valid, or an observer estimate of the sensed engine operational parameter, if the sensor signal is invalid.
