This paper proposes the comparison among different sensorless position estimation strategies suitable for permanent magnet assisted synchronous reluctance machine drives. A machine of such type was designed and optimized aiming at improving its sensorless performance, besides minimizing the torque ripple and maximizing the power factor. Different sensorless solutions for the estimation of the magnetic flux linkage and for tracking the rotor angle are investigated and their performance compared in computer simulations. Experimental results are reported for the PM-assisted synchronous reluctance motor drive example.

Abstract
This paper proposes the comparison among different sensorless position estimation strategies suitable for permanent magnet assisted synchronous reluctance machine drives. A machine of such type was designed and optimized aiming at improving its sensorless performance, besides minimizing the torque ripple and maximizing the power factor. Different sensorless solutions for the estimation of the magnetic flux linkage and for tracking the rotor angle are investigated and their performance compared in computer simulations. Experimental results are reported for the PM-assisted synchronous reluctance motor drive example.
