Performance Analysis of Induction Motor using DTC Technique

Abstract

Abstract

Direct Torque Control is a control method used for high-performance torque control in AC drive systems. The standard DTC drive includes a couple of hysteresis comparators, a flux and torque estimator and a selection table for voltage vectors. Torque and flux are governed simultaneously by implementing appropriate voltage vectors, and de-coupling control of torque and flux can be accomplished by restricting these amounts within their hysteresis bands. The DTC requires the flux and torque estimator. A voltage vector modulator is then used to realize the reference voltage vector. This project's work is to study, evaluate and compare the different techniques applied to the induction machines by the DTC-SVM. Assessment is carried out on the basis of drive efficiency, which involves dynamic torque and flux responses, feasibility and system complexity. To check the outcomes, a simulation program was created.  The responsibility cycle of the inverter can then be calculated the use of the PWM approach of the gap vector for immediate torque manipulate, that's pretty awesome from FOC (field Orientation control), the recommended method could be very promising.
