Data is obtained with open-loop voltage com- mands at multiple speeds. A new reference frame is proposed that presents advantages similar to the standard d − q frame, but without the need for a position sensor. The method exploits carefully derived linear parameterizations and a least-squares algorithm. In one case, overparameterization is resolved using elimination theory. Overall, the parameters identified using the new procedure are found to be very close to those obtained with position sensors. The approach is potentially applicable to other types of synchronous motors as well.Show less >
