DSP In the Loop implementation of an enhanced Direct Torque Control for Induction Motor drive

This paper deals with an enhanced Direct Torque Control strategy for induction motor drive. The proposed approach uses a more precise switching table based on twelve sectors and modified hysteresis controllers. Processor In the Loop technique is performed using MATLAB with Code Composer Studio and F28069M development board. Therefore, this work proposes an experimental validation of an enhanced algorithm for Direct Torque and flux Control. Also, it offers a comparison to the conventional Direct Torque Control strategy. Processor In the Loop results, show that modified Direct Torque Control strategy improves torque and flux dynamic and enhances waveforms quality. So flux and torque ripples and harmonic distortion of the currents are reduced.
