Abstract

A rotor position estimator for a synchronous reluctance machine (SynRM) is presented. The rotor position is formulated in polar stator-current coordinates and is directly calculated based on stator current measurements and voltage commands. Only two machine parameters are required, stator resistance and average inductance. The scheme is easy to implement and has good dynamical and load rejection characteristics. An analysis and experimental results are presented.
