Le contrôle MLI de vitesse pour un moteur Brushless DC

Abstract

This end of study project in Master Electromechanics is focused on PWM speed control for a Brushless DC motor. Mathematical models were developed and subsequently used to obtain the simulation parameters. The PWM control technique is accomplished with use under software / PSIM. The parameters of the method that is used to develop further simulations. To meet the needs of this dissertation, our work is mainly structured around four chapters: The first chapter is devoted to a definition of the BLDC with their operating principle, and to quote their characteristics and constitution. The second chapter Mathematical modeling concerning the BLDC machine mathematical and mechanical equation. The third chapter the PWM control technique and definition of static converters (inverter). PI regulation loop. The fourth chapter simulation association brushless machine converter and regulation loop for speed control. This memoir ends with a conclusion which summarizes all the results obtained in this study and which presents some perspectives.
