Torque and stator flux ripples minimization for direct torque control of PMSM by using space vector modulation

International audienceIn this article, we present the strategy of the direct Torque control (DTC) of the permanent magnets synchronous machine (PMSM) with regulators in hysteretic controlled by the technique SVM: Space Vector Modulation that use the hysteresis comparator for the determination the voltage module and its angle. This method of control allows reducing the fluctuations at the level of the torque and of the flux also in the low speed contrary with control of the classical DTC where the frequency of switching is incontrollable. Simulations results obtained allow demonstrate the performances of this command especially in the behavior of the couple and the flux
