A control system for an engine operatively coupled with a propeller and methods for controlling an engine operatively coupled with a propeller are provided. In one example aspect, the control system includes a controller and an electric propeller governor. The electric propeller governor includes a motor operatively coupled with a flyweight governor spring. The motor is communicatively coupled with the controller. The controller is operable to receive data indicative of the speed of the propeller, determine if the measured speed exceeds a propeller speed threshold, and if the threshold is exceeded, the controller is configured to change a propeller speed set point. Particularly, the controller can cause the motor to change the preload on the flyweight governor spring, which in turn causesadjustment of the propeller speed set point. In this way, propeller speed overshoot is prevented during fast acceleration of the engine.

    提供了一种用于与推进器可操作地联接的发动机的控制系统以及用于控制与推进器可操作地联接的发动机的方法。在一个示例方面,控制系统包括控制器和电动推进器调速器。电动推进器调速器包括与飞重调速器弹簧可操作地联接的马达。马达与控制器通信地联接。控制器可操作以接收指示推进器的速度的数据,确定所测量的速度是否超过推进器速度阈值,并且如果超过阈值,则控制器构造成改变推进器速度设定点。特别地,控制器可以使马达改变飞重调速器弹簧上的预载,这又导致推进器速度设定点的调节。以此方式,在发动机的快速加速期间防止推进器速度超调。
