Investigations on flux estimation methods for stator current based MRAS speed estimator for induction motor drive

In this paper, a detailed comparative study on the performance of an encoder-less vector control induction motor drive is presented. The performance is compared using two types of rotor flux vector estimation models: voltage model and current model. Speed information of the estimators is used for speed control of motor. MATLAB software is used to model the complete system and to perform the analysis.
