Abstract

An electric machine control system includes a control unit, wherein the control unit includes inputs for a POR voltage feedback, an electric machine current feedback, a PMG feedback, and an input speed feedback. A protection unit includes inputs for: the POR voltage feedback, the electric machine current feedback, the PMG feedback, and the input speed feedback. At least one trip connection connects between the control unit and the protection unit. A method of generator control includes receiving an input speed feedback, a generator line contactor (GLC) auxiliary feedback, a generator control switch (GCS) feedback, and the weight on wheels feedback in a control unit. The method includes determining within the control unit if voltage regulation and/or frequency regulation should be enabled independent from a protection unit operatively connected to the control unit.
