Abstract
A control system for a generator of an electric drive is provided. The control system may include a converter circuit configured to communicate with one or more phases of a stator of the generator, and a controller in communication with the converter circuit and an engine associated with the electric drive. The controller may be configured to determine an operational state of the electric drive based on at least engine speed, and engage one of a map-lookup control scheme and a fixed-theta off control scheme for operating the generator based on the operational state of the electric drive.
