Saliency-based sensorless control for AC induction machines in wind applications

Abstract

The master thesis explores the uses of saliency-tracking methods for the sensorless control of induction machines in wind applications in the low speed region. The study is focused on a feasibility analysis of the technique under the typical speed/load conditions. In order to improve the system accuracy as well as extended load operation, decoupling of saturation-induced saliencies is also considered
