Abstract :
This paper describes an SVM-DTC control scheme of an induction motor. Combining the Space Vector Modulation (SVM) and Direct Torque Control (DTC) resulting a minimal torque ripple compare to classical DTC. Investigation of speed and torque performance of the induction motor within base speed and in field weakening region are verified in the experiment. The stator flux in field weakening region is weaken using “1/ ωr” method. The overall experiment is conducted using a drive system base on TMS320F28335 floating point microcontroller and dynamometer as a load of the motor.
