Abstract	The primary objective of this paper is to implement a sensorless indirect stator field oriented control (ISFOC) of induction motor drive with rotor resistance tuning. Indeed, the proposed method for simultaneous rotor speed and rotor resistance estimation is based on Luenberger observer (LO). In order to estimate the rotor speed and the rotor resistance, an adaptive algorithm based on Lyapunov stability theory by using measured and estimated stator currents and estimated stator flux is proposed. The suggested control scheme, as a result, achieves a sound performance with computational complexity reduction obtained by using the analytical relation to determine the LO gain matrix. Again, the observer is simple and robust, when compared with the previously developed observers, and suitable for online implementation. For current regulation, however, this paper
