Contribution à la commande de la machine asynchrone par DTC et logique floue.

Abstract

In this memoir we present: - A modeling of the induction Machine (IM) and his supply which is made up of a three phase voltage inverter. - A Direct stator Flux and Torque Control (DTFC) strategy applied to the IM. Two approach for the fuzzy logic regulation are used - In first approach we replace the hysteresis controllers for DTC by a fuzzy regulator. - For the second approach fuzzy PI speed regulation is used to replace the conventional PI regulator.
