    Abstract :

    This paper manages change of Direct Torque Control technique for induction motor (IM) drive. Since the primary drawbacks of the established DTC are high torque/flux ripples and current contortion, this paper embeds the space vector modulation keeping in mind the end goal to decrease the ripples by keeping up a consistent switching frequency. Furthermore, the fuzzy logic controllers will supplant the conventional proportional integral (PI) controllers for stator motion and torque direction and to guarantee a precise reference following and a strong reaction against various vulnerabilities, for example, outer aggravation and parameters variety. Moreover, a stator flux based Model Reference Adaptive System (SF-MRAS) is planned as a sensorless calculation for the estimation of rotor speed. This estimator can enhance the execution of the controlled framework by expanding its unwavering quality and diminishing the cost of the speed sensor. The worldwide control calculation has been explored by means of numerical reenactment and continuous experimentation utilizing Matlab/ Simulink with dSpace 1104 flag card.
