Direct torque control with SVM based a fractional controller: Applied to the induction machine

This work presented in article is focused on the control of asynchronous induction machine, in optics to use in the energy wind production. We recall to the beginning the principle of operation and the modeling of the machine. We point out then the principle of traditional DTC control with space vectorial modulation of the inverter (SVM) which we use for the control of the machine without and with speed regulation (open Loop). The originality of our approach lies in the fact that magnetic flow, the Torque and speed are to control with a fractional pi regulator. We describe the simulations carried out with traditional PI regulator and fractional PI regulator and we present the results obtained with the two regulator used before opening prospects for future work.
