MRAS Based Speed Sensorless Control of Induction Motor Drives

Authors: Nadia Bensiali, Amar Omeiri, Nadia Benalia


The recent trend in field oriented control (FOC) is towards the use of sensorless techniques that avoid the use of speed sensor and flux sensor. Sensors are replaced by estimators or observers to minimise the cost and increase the reliability. In this paper an anlyse of perfomance of a MRAS used in sensorless control of induction motors and sensitvity to machine parameters change are studied.

Keywords: Stability Analysis, adaptive observer, induction motor drive, MRAS
