DTC based on SVM for induction motor sensorless drive with fuzzy sliding mode speed controller

By using the direct torque control (DTC), robust response in ac drives can be produced. Ripples of currents, and flux are oberved steady state. space vector modulation (SVM) applied DTC used for a sensorless induction motor (IM) with fuzzy sliding mode speed controller (FSMSC) is studied this paper. This minimize torque, flux, current pulsations To estimate rotor stator model reference adaptive system (MRAS) that designed from identified voltages currents. The FSMSC to enhance efficiency robustness presented system. transient advantage maintained, while better quality steady-state performance produced implementation wide range. drive performances have been checked by Matlab Simultaion, successful results obtained. It deduced proposed produces than classical DTC.
