Vector Control Of Induction Motor (IM) is based on dynamic-state relationships. The torque, stator flux and Induction Motor Drive speed will be highly variable under transient and stable operation conditions. From the various induction speed control methods such as pole change, frequency variation, variable rotor resistance, variable stator voltage, constant voltage / frequency control, slip recovery method, etc. Direct Torque Control (DTC) is one of the methods used by Vector Control to control torque and speed of the induction motor. Vector control is better than scalar control because the DTC method can control not only the magnitude but also the position of voltage, currents and flux instantaneously. This method is mainly suggested for controlling torque and speed because of dynamic performance of the induction motor. Thus, high quality of torque, stator flux and rated speed of the Induction Motor (MT) s achieved.
