The Evaluation of Online Observer System of Synchronous Reluctance Motor Using a Coupled Transient FEM and Preisach Model

This study deals with the dynamic characteristics analysis of synchronous reluctance motor (SynRM) using finite element method in which the moving mesh technique is considered. The focus of this paper is to show the appropriate of online observer system for position sensorless control of a SynRM under saturation and iron loss. Comparisons are given with angle of the observer and that of proposed FEM and Preisach model of synchronous reluctance motor, respectively. The position sensorless control system is realized, and the effectiveness of the observer system is verified by experimental results.
