Abstract :

The aim of this paper is to review the origin and developments of DTC method which is very useful method as compared to field oriented control . The direct torque control is one of the excellent control strategies available for torque control of induction machine . In this method direct torque control is achieved by selecting suitable inverter switching voltage vector from a lookup table. But drawback of this method is that it produces toque ripples.Also the switching frequency of inverter switches is not constant. Many methods have been proposed to address these issues of DTC. This paper reviews various methodologies which are suggested to modified the performance of basic DTC induction motor drive.
