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 determin...


1. A system for controlling fuel flow rate to a fluid-operated actuator and to a combustor in a gas turbine engine, comprising: a fuel metering pump coupled to receive fuel, and further coupled to receive a pump command representative of a desired fuel flow rate, the fuel metering pump operable, upon receipt of the pump command, to supply fuel at the desired fuel flow rate;a control unit including a control law and a state estimator, the state estimator comprising a software model of the fuel metering pump and an software model of the fluid-operated actu...
