This paper describes the implementation of multirate sampling technique for carrier space vector pulse width modulation based direct torque control (CSVPWM DTC) of induction motor (IM) drive with an objective to reduce the electromagnetic torque ripple. The benefit of the proposed technique for CSVPWM DTC based IM drive; it gives lower torque ripple as compared to single rate sampling technique. In...
This paper illustrates the implementation of the direct torque control (DTC) strategy for induction motor (IM) drive using carrier space vector pulse width modulation technique. In the present work, the algorithm used for DTC based control of IM is Carrier Space Vector Pulse Width Modulation (CSVPWM) technique. A comparison of performance between standard and carrier based SVPWM techniques have been...
In the present work a novel strategy for optimum design of flux and torque controller for carrier space vector pulse width modulation based direct torque control (CSVPWM DTC) of induction motor (IM) drive has been implemented. Two positive and one negative torque slope levels per half the switching period has been predicted for CSVPWM DTC IM drive based on which a new optimal control strategy is proposed...
