Abstract :

In the industries induction motors are widely used, because they are reliable, rugged and cheap. Induction motor drive requires suitable converters to produce the required speed and torque without ripples. In this paper direct torque control (DTC) scheme of induction motor (IM) and its comparative study using (DTC-SVM) technique under varying dynamic conditions are discussed. Direct Torque Control is a restraint technique used to obtain high performance torque control. The rule is based on simultaneously decoupling of stator flux and electromagnetic torque. The DTC-SVM can be implemented using closed loop torque control system, for minimization of torque ripple. In this case estimation of the stator and rotor flux is needed. Thus, all the parameters of the induction motor must be recognized. Multilevel inverter has developed recently as a very important alternative option in the field of medium-voltage, high-power control and also for improving the THD (total harmonic distortion) by reducing the harmonics. In this paper a Simulink model is developed by using the DTC - SVM technique for controlling the speed of induction motor and verified using MATLAB.
