Abstract: A combination of Direct Torque Control (DTC) and Space Vector Modulation (SVM) for an Induction Motor (IM) drive is defined in this paper. A two-level SVPWM inverter is delivered to the induction motor drive. Using IM model in the stator D-Q axes reference frame. The inverter voltage is achieved based on input- output feedback linearization control. This paper signifies a Fuzzy Logic Controller (FLC) for the proposed system. The inputs to the fuzzy logic controller are the variables of speed error and change of speed error whereas the output is change in switching torque. The effectiveness and validity of the proposed control approach, attained from the variable methods those are DTC-SVM and FUZZY LOGIC CONTROL are compared by simulation results. 

Keywords: Direct Torque Control (DTC), Adaptive Stator Flux Observer Feedback Linearization, Robust, Space Vector Modulation, And Fuzzy Logic Control.
