摘要：A system and method for position sensorless control of an AC electric machineis disclosed. A drive system for driving an AC electric machine provides a primary current
excitation to drive the AC electric machine, the primary current excitation comprising acurrent vector having a magnitude and angle. The drive system injects a carrier signal tothe AC electric machine that is superimposed onto the current vector, with the carriersignal being selected to generate a carrier response signal that has sensitivity tomagnetic alignment information of the AC electric machine at its operating point. Thedrive system measures at least one magnetic alignment signature of the AC electricmachine from the generated carrier response signal and controls an orientation of thecurrent vector using the measured at least one magnetic alignment signature, so as toachieve a desired magnetic operation of the AC electric machine.
