Full text: PDF


This paper is an attempt to explore the possibility of using Extended Kalman Filter trained recurrent neural network for speed estimation of an induction motor drive. Also, the speed estimation is made robust by simultaneously adapting the rotor resistance and the rotor flux by using the same neural network. The training is very fast as it requires only one iteration. The proposed scheme is studied on an induction motor and it is seen that it gives better performance as compared to already existing algorithms in literature.
