摘要： A method for controlling the speed of an engine driving a generator supplying electrical current to a load includes the steps of monitoring the current, increasing the speed when the current increases and decreasing the speed when the current decreases. The governor apparatus used to carry out the method includes a microcontroller having a current and frequency look-up table embedded in it. For some part of the monitoring step, the engine runs at a first speed, e.g., idle speed, or some moderate speed above idle speed. The increasing step includes detecting an increase in the current to a value, determining from the look-up table the frequency corresponding to the value and increasing the speed of the engine until the frequency of the current is the frequency corresponding to the value. To state it in other words, the new method and apparatus control the engine at a modest speed when the generator is unloaded or lightly loaded and increases engine speed and current frequency with increases in generator load.

摘要翻译： 用于控制向负载提供电流的发电机驱动发动机的速度的方法包括监视电流的步骤，当电流增加时增加速度，并且当电流减小时降低速度。 用于执行该方法的调速器装置包括具有嵌入其中的电流和频率查找表的微控制器。 对于监测步骤的某些部分，发动机以第一速度（例如空转速度）或高于怠速速度的中等速度运行。 增加步骤包括检测电流增加到一个值，从查找表中确定与该值对应的频率并增加发动机的速度，直到电流的频率是与该值对应的频率。 换句话说，当发电机卸载或轻载时，新的方法和装置以适度的速度控制发动机，并随着发电机负载的增加而提高发动机转速和电流频率。
