Abstract
A sensorless drive has serveral advantages; low cost and mechanical simplicity. This paper studies a comparison between observer and Kalman filter for sensorless speed control of induction motor. The simulation result generally shows good performances in the both sensoless control strategies. In case of considering noises, EKF algorithm shows a better performance. In case of considering parameter variation, observer algorithm shows a better performance.
