Abstract

In this paper simulation of a novel Space Vector Modulated Direct Torque Control (DTC-SVM) of sensorless induction motor is presented. Classical direct torque control (DTC) of induction motor drive is simple in nature and known to produce quick response but there is usually undesired torque and flux ripple. This paper introduces an improved flux and torque estimator based DTC-SVM which has a low-pass filter based voltage model with compensations of amplitude and phase. The proposed scheme is able to reduce the flux and torque ripple significantly while maintaining the simplicity and robustness of conventional DTC at the most.
