Induction motor is widely used as an industrial asynchronous drive. This paper presents a technique to control induction motor by use of Direct Torque Control. (DTC), DTC is one of the excellent control strategies of torque control in asynchronous drives. It controls both electromagnetic torque and flux directly and independently. DTC is considered as an alternative to the Field Oriented Control (FOC) or Vector Control Technique. These two control strategies are different on their principle of operation. However, their objectives are the same. A model of DTC scheme for an asynchronous drive has been demonstrated. SIMULINK / MATLAB has been used to implement the DTC scheme.
