Abstract
This paperproposes design and simulation of an immediate torque control induction motor drive system based on space vector modulationand PI controller to control speed, torque and to shrink torque ripples. For controlling these the precept used here is thesimultaneously decoupling of the stator flux and electromagnetic torque. Hysteresis comparators used by DTC drives undergofrom high torque ripple and variable switching frequency. The proposed SVM based DTC procedure reduces torque ripples andretain DTC transient deserves reminiscent of fast torque response. The groundwork of the SVM-DTC system is the calculation of therequired space vector of voltage to compensate the errors in flux and torque and its generation utilising the SVM for each sampleperiod. The performance of this process in this paper is established by using simulation utilizing Simulink software.
