Abstract: The Direct Control (DTC) technique is deemed as one of the important control techniques that have been utilising in induction motors in order to achieve a high-speed response as well as fast torque response. Conversely, the classical DTC has some main drawbacks including a high level of torque ripple and stator current harmonics. Therefore, this study presents a DTC method coupled with space vector modulation based on the reference flux and torque to overcome such issues. In this projected control method, PI torque and PI flux controllers have been designed in order to compare an estimated flux and torque responses with reference flux and torque, respectively. This proposed technique has been compared with Field Oriented Control (FOC) technique to comprehend the impact of each technique on induction motor drives. DTC-SVM and FOC have been implemented by using a MATLAB Software package to simulate induction motor dynamics to produce findings for evaluation. The ostensible comparison of both techniques is shown with the simulation results.
