Analysis of Torque and Flux Ripple Factor for DTC and SVM - DTC of Induction Motor Drive

Recently induction motor control techniques have gained their importance in many industrial applications. To obtain fast dynamic torque & flux response Direct Torque Control (DTC) of Induction Motor is implemented using steady state & transient input conditions in MATLAB/Simulink. In order to control both torque and stator flux directly, they need to be predicted to limit them within hysteresis band closed to desired values. This can be realized by selecting suitable sector in space vector modulation. It can perceive that the torque is dependent on the stator flux, rotor flux and the angle between their vectors. In this paper, we have simulated and analysed torque and flux ripple factor for different conditions.
