Le prochain séminaire des Ponts D’EULER aura lieu à ISAE-Supméca le 30 juin à 13h15 en amphi Josette Genevois. Il sera donné par Belkacem Ould Bouamama et portera sur Les Bond graphs pour la conception intégrée des systèmes de supervision.
Abstract: Bond graph is a powerful tool well known for dynamic modelling of multiphysical systems: Recently several fundamental theories have been developed for using a bond graph model not only for modeling but also as a real integrated tool for control, and Prognosis and Health Management (PHM) of mechatronics systems.
After presentation of my research group, this conference presents a synthesis of those new theories which exploit some particular properties (such as causal, structural and behavioral) of this graphical methodology. Based on a pedagogical and real applications, it will be shown how from a physical system (not a transfer function or state equation) and using only one representation (Bond graph), the following results can be performed: modeling (formal state equations generation), Control analysis (observability, controllability), robust diagnosis analysis (automatic generation of robust fault indicators based on LFT Bond graphs) and prognosis. The presentation will be illustrated by pedagogical and real industrial applications.
