Etude et commande d’une machine asynchrone double étoile

Abstract

For applications of strong power, the multiphase machines are increasingly used for reasons of reliability and segmentation of power. We propose here to study the more running example of the multiphase machines, the dual star asynchronous machine. This memory, initially presents a study of modeling and supply of the DSIM, applying three strategies of voltage source inverter control sine triangle PWM. Field oriented control of the DSIM supplied with two voltage source inverters, using PI regulators presents some disadvantages such as the sensitivity to parametric uncertainties of the machine and their variations. Against of this disadvantage, and to improve the system performances, we applied robust techniques of control: sliding mode.
