Query: Signal injection and averaging for position estimation of
  Permanent-Magnet Synchronous Motors   Sensorless control of Permanent-Magnet Synchronous Motors at low velocity
remains a challenging task. A now well-established method consists in injecting
a high-frequency signal and use the rotor saliency, both geometric and
magnetic-saturation induced. This paper proposes a clear and original analysis
based on second-order averaging of how to recover the position information from
signal injection; this analysis blends well with a general model of magnetic
saturation. It also experimentally demonstrates the relevance for position
estimation of a simple parametric saturation model recently introduced by the
authors.
