Review of position estimation methods for IPMSM drives without a position sensor part I: Nonadaptive methods

Abstract

This paper presents a review in state of the art techniques for position sensorless permanent magnet synchronous motor drives. In particular nonadaptive methods like estimators using monitored stator voltages or currents, flux estimators and back-EMF based estimators are described. Furthermore the authors give an overview for current methods to the… (More)
