“…The authors use simulations and experimental tests to validate the proposed method. In [62,63], the authors showed that the conventional DTC has a low number of voltage vectors applied to the machine, which causes undesirable oscillations of the torque, flux and current. This work shows that improved performance can be achieved by using a new DTC algorithm, based on the application of SVM for fixed time intervals.…”

Conventional direct torque control (DTC) is one of the excellent control strategies available to control the torque of the induction machine (IM). However, the low switching frequency of the DTC causes high ripples in the flux and torque that leads to an acoustic noise which degrades the control performances, especially at low speeds. Many direct torque control techniques were appeared to remedy these problems by focusing specifically on the torque and flux. In this paper, a state of the art review of various modern techniques for improving the performance of DTC control is presented. The objective is to make a critical analysis of these methods in terms of ripples reduction, tracking speed, switching loss, algorithm complexity and parameter sensitivity. Further, it is envisaged that the information presented in this review paper will be a valuable gathering of information for academic and industrial researchers.

“…The basic principle of the direct torque control (DTC) is characterized by the direct choice of the stator voltage vectors according to the differences between the references of the torque and the stator flux and their real values. Current controllers followed by a PWM comparator are not used in DTC control systems; and the parameters of the machine are not used also except for the stator resistance of the motor [3].…”

Traditional Direct torque control (DTC) has the rapid torque response, better robustness. However it has larger torque ripple and flux ripple at low speed because of the inverter switching frequency varying with the speed. The deadbeat DTC can achieve the given torque and flux at the end of a sampling period. And it can reduce the ripple of torque and flux. The simulation and experiment results show that the current distortion can be improved and the flux ripple and torque ripple can be reduced by Deadbeat DTC which inherits the rapid response of traditional DTC.
