In this paper, a new duty cycle control method is proposed to reduce torque and flux ripples of the conventional direct torque control (DTC). In the proposed method, a new approach is initially introduced to select the appropriate active voltage vector (VV) precisely. Then by inserting the zero VV along with the selected one, a finite set of new candidate VVs with different duty cycles are synthesized...
Today, The Direct Torque Control (DTC) is a common solution in modern induction motor drives. Because of the low number of available active voltage vectors, the DTC method has high flux and torque ripple. In this paper, an improved model predictive DTC method will be proposed to decrease both torque and flux ripples without the use of weighting factor. This method is based on the combination of the...
