The operation of the induction motor can be analyzed similar to a DC motor through direct torque control method. The axis control with variable speed in low power applications with these technological projections, various command approaches have been developed by the scientific community to master in real time, the flux and the torque of the electrical machines, the direct torque control (DTC) scheme being one of the most recent steps in this direction. This scheme provides excellent properties of regulation without rotational speed feedback. In this control scheme the electromagnetic torque and stator flux magnitude are estimated with only stator voltages and currents and this estimation does not depend on motor parameters except for the stator resistance. Induction motor has been simulated in stationary d-q reference frame and its free acceleration characteristics are drawn. Review has been done to study the recent improvements in DTC scheme which somehow is able to overcome the drawbacks of conventional one. The space vector modulation technique (SVPWM) is applied to inverter control in the vector control based induction motor drive system, thereby dramatically reducing the torque ripple.
