| Abstract: | Senseless induction motor drives are widely used in industry for their reliability and flexibility, particularly in hostile environment. However, the performance of many of previously developed observer based speed sensors in very low speeds of IM drives was not satisfactory. In this paper we present two types of MRAS based speed estimators, one based on the rotor flux and the other based on the back EMF. The estimated speed is used as feedback in a vector control system. The MRAS approach has the immediate advantage in that the model is simple, presents the theory, modelling and this method because eliminates the produced error in the speed adaptation, is more stable and robust. Simulation results of the proposed MRAS speed observer based sensorless field-oriented induction motor drives. The performances of both techniques are evaluated in indirect vector control system and the results are presented.
