SYSTEM AND METHOD FOR CONTROLLING A FUEL FLOW TO A GAS TURBINE ENGINE

A computer-implemented method for controlling a fuel flow to a gas turbine engine of an aircraft includes determining a control initiated fuel flow demand that is based, at least in part, on an operator command. In addition, the method includes determining a first rate of change of fuel flow demand...

Zusammenfassung:	A computer-implemented method for controlling a fuel flow to a gas turbine engine of an aircraft includes determining a control initiated fuel flow demand that is based, at least in part, on an operator command. In addition, the method includes determining a first rate of change of fuel flow demand based, at least in part, on a tracking error of the gas turbine engine that indicates a difference between a desired rotational speed and an actual rotational speed. The method also includes integrating the first rate of change of fuel flow demand to determine a tracking error fuel flow demand. In addition, the method includes summing the control initiated fuel flow demand and tracking error fuel flow demand to determine a composite fuel flow demand. The method also includes controlling a fuel flow to the gas turbine engine based, at least in part, on the composite fuel flow demand. 种用于控制到飞行器的燃气涡轮发动机的燃料流的计算机实施方法包括确定控制起始燃料流需求，所述确定至少部分基于操作员命令。此外，所述方法包括至少部分基于指示所要旋转速度与实际旋转速度之间的差的所述燃气涡轮发动机的跟踪误差来确定燃料流需求的第改变速率。所述方法还包括对燃料流
