A design method of full-order extended electromotive force observer for sensorless control of IPMSM

Abstract

A full-order extended electromotive force (eemf) observer for sensorless control of IPMSM and a design method of one have been proposed. This paper proposes a new design method of the full-order eemf observer by taking a new look at the error system of one. The simulation results show that a new design method of the full-order eemf observer is very useful.
