Speed-Sensorless AC Drive Based on MRAS Scheme with a Novel Observer

Abstract:

This paper proposes a new flux observer, which combines a current model and a modified voltage model based on an adaptive feedback compensation method. And an adaption algorithm based on MRAS for simultaneous speed estimation is presented. The effectiveness of the proposed method is tested through simulation and is experimentally verified.
