| Titre : | Commande floue optimisée de la suspension active d’un véhicule | | Type de document : | texte manuscrit | | Auteurs : | Faiza Yousfi, Auteur ; Zineb Yousfi, Auteur ; Lakhdar Mokrani, Directeur de thèse | | Editeur : | Laghouat : Université Amar Telidji - Département d'électrotechnique | | Année de publication : | 2022 | | Importance : | 60 p. | | Format : | 30 cm. | | Accompagnement : | +1 CD ROM Optique Némérique | | Note générale : | OPTION : COMMANDE ELECTRIQUE
OPTION : AUTOMATIQUE ET SYSTEMES | | Langues : | Français | | Résumé : | The main objective of this memoir is the modeling and optimized fuzzy control of a Vehicle Active
Suspension (VAS) system. This system has been designed to increase the safety level of the vehicle
and to provide greater comfort to the passengers by reducing vibrations regardless of the road
profile. Firstly, the mathematical models of the active suspension systems were established for
different cases of ¼, ½ and the whole vehicle. To improve the performance of the VAS system, two
types of controllers (a PID and a fuzzy PID ) were used to modulate the forces of the suspension
actuators. The problem of tuning the gains of these controllers was overcome by optimizing the
oscillations of the suspended mass using 'OPTIMTOOL' of MATLAB. Next, an electromagnetic
actuator based on a field oriented Permanent Magnet Synchronous Motor (PMS) was used to
generate the force profile required for good active vehicle suspension. A simulation study was
carried out on the vehicle quarter model of an SAV system in MATLAB /SIMULINK. The results
obtained show the good ability of this system to damp well the oscillations due to the disturbances
caused by the road profile. | | note de thèses : | Mémoire de Master en élctrotechnique |
