Sensorless control of PMSM drives for hybrid electric vehicles
Paper i proceeding, 2004

This paper considers the implementation of a speed and position estimator for a permanent-magnet synchronous machine in a hybrid-electric vehicle application. A modified variant of the estimator of phase-locked loop type, previously developed by Harnefors and Nee, is presented, in order to take into account effects of saliency and operation in the whole speed region. Furthermore, design rules for all parameter settings are given. Based on drive-cycle simulations, important operating points are chosen for evaluation, with good results, on an existing experimental setup.
