Abstract
There is provided a system and method for controlling an electronic device. An exemplary method comprises employing a look-up table to derive waveform value data for a multi-phase reference waveform. The exemplary method also comprises employing the look-up table to derive waveform value data corresponding to harmonic data for the multi-phase reference waveform. Harmonic data is injected into the multi-phase reference waveform to produce a harmonic reference waveform. The exemplary method additionally comprises generating a plurality of control signals from the harmonic reference waveform.
