Abstract:
1. A method of controlling a generator of an electric drive associated with an engine, the method comprising the steps of: determining a mode of operating the generator based on a speed of the engine; engaging a single pulse mode of operating the generator if the engine speed is relatively high; engaging a current regulation mode of operating the generator if the engine speed is not relatively high; providing a first signal for operating the generator based on a map-lookup control scheme; providing a second signal for operating the generator based on a fixed-theta off control scheme; determining an operational state of the electric drive based on output characteristics of the engine; and selectively enabling one of the first and second signals for controlling the generator based on the detected operational state of the electric drive.
