1. A motor control system comprising:

  • control circuitry configured to generate control signals to control a permanent magnet motor based at least in part upon a comparison of a flux-producing current component of a power waveform supplied to the permanent magnet motor and a flux-producing component of a command reference current value and to determine the angular position of the stator magneto-motive force based at least in part on a comparison of a torque-producing current component of the power waveform and a torque-producing component of the command reference current value.
