Simple DTC cannot be used because it requires at least 40kHz just to operate properly. Otherwise the torque value gets unstable, oscillating between positive and negative values. The solution for such a problem is to complement DTC with SVM (space vector modulation) for generating the correct space voltage vector required for driving the motor. Thus, src_full_DTC will be left as it is and a new src_DTC-SVM will be created instead.
