Sensorless Control of Induction Motor: Design and Stability Analysis

Authors: Nadia Bensiali, Erik Etien, Amar Omeiri, Gerard Champenois


Adaptive observers used in sensorless control of induction motors suffer from instability especally in regenerating mode. In this paper, an optimal feed back gain design is proposed, it can reduce the instability region in the torque speed plane .

Keywords: Induction motor drive, adaptive observer, regenerating mode, stabilizing design.
