Abstract :
A novel DTC control scheme for interior permanent magnet synchronous machines is proposed in this paper, which features low torque and flux ripple and almost fixed switching frequency, by means of space vector modulation (SVM). The torque and flux ripples have been significantly reduced if compared with those of the basic DTC reported in the literature.
