Abstract: A system and method for controlling an electrical device is provided. The method comprises receiving three phase power from a source, decomposing signals representative of power in each phase of the three phase power to provide a positive-sequence component of each phase and tracking the positive-sequence component of each phase via a phase locked loop and a tracking filter.
