WOUND FIELD SYNCHRONOUS MACHINE SYSTEM WITH INCREASED TORQUE PRODUCTION AND METHOD OF OPERATION

摘要

A method of operating a wound field synchronous machine system includes comparing a desired motion command signal with at least one of a feedback position signal and a feedback velocity signal to generate a torque command signal by a motion controller. A current command signal is then generated by a current command generation module including additional harmonics of up to a six-step waveform as a function of the feedback position signal. A current regulator regulates a processed current feedback signal to the current command signal to generate a voltage command.
