Abstract
A controller-implemented method of controlling a machine having a rotor coupled to an engine through a variable transmission is provided. The controller-implemented method may include receiving a desired rotor speed, determining an engine load of the engine, adjusting an engine speed of the engine based on the engine load and one or more predefined efficiency points, and adjusting a gear ratio of the variable transmission based on the engine speed and the desired rotor speed.
