| Titre : | Flatness-based control of a PEM fuel cell air-feed system | | Type de document : | document multimédia | | Auteurs : | Anfal Lina Bait, Auteur ; Bachir Bendjedia, Directeur de thèse | | Editeur : | Laghouat : Université Amar Telidji - Département d'électrotechnique | | Année de publication : | 2024 | | Importance : | 60 p. | | Accompagnement : | 1 CD ROM Optique Némérique | | Note générale : | Automation and Systems | | Langues : | Anglais | | Mots-clés : | Fuel cell Flatness-based control Nonlinear dynamics, Proportional-integral controller, System stability | | Résumé : | This study develops a flatness-based control strategy for regulating the oxygen excess ratio (λO2) in fuel cell systems. Initially, a reduced four-state model and its linearized version are established, highlighting significant deviations between linear and nonlinear models under varying operational points. While flatness control based on the linear model shows perfect tracking of λO2, application to the nonlinear model reveals significant errors. Integration of a Proportional-Integral (PI) controller enhances precision by incorporating λO2 error, underscoring the role of robust control strategies in optimizing fuel cell performance. | | note de thèses : | Mémoire de master en électrotechnique |
