A novel speed estimation algorithm for induction machines

Abstract In this paper, a novel speed estimation algorithm mathematically derived from current model of an induction motor is presented. The method used here is more advantageous than other techniques due to its simplicity. In this technique, since the speed varies slowly as compared to electrical variables such as currents and fluxes, the speed is assumed to be an unknown constant. Based upon this assumption, a definition of a new speed estimator is reported and its performance is confirmed experimentally.
