摘要：
According to the present invention, a fuel control has an electronic primary control for scheduling a flow of fuel to an engine in a primary mode and hydromechanical secondary control for scheduling the flow of fuel to the engine in a backup mode. The fuel control also has a tracking piston and link whose position is responsive to the HMU during the operation of the electronic primary control. The tracking piston and link effectively changes the power lever angle sensed by the HMU so that in the event of a transfer of control from the electronic primary control to the HMU, changes in the scheduled fuel flow to the engine are minimized.
摘要（中）：
根据本发明，燃料控制具有用于调度主模式的发动机的燃料流的电子主控制和用于在备用模式下调度到发动机的燃料流的液压机械二次控制。 燃料控制还具有跟踪活塞和连杆，其位置在电子主控制的操作期间响应于HMU。 跟踪活塞和连杆有效地改变由HMU感测到的动力杆角度，使得在将控制从电子主控制传递到HMU的情况下，到发动机的调度燃料流量的变化被最小化。
