Plate-forme d'aide à l'éco-conception de systèmes multiphysiques : démarche énergétique pour la validation et la réduction de modèles

Abstract : Nowadays, technological evolutions are leading engineers to model increasingly multiphysic andcomplex phenomena throughout the systems design process: the V-cycle. Adapted and efficientsystems design tools are therefore necessary in order to reduce time-to-market, while stillensuring fully developed and energy-saving products. First, this work describes the set-up of avirtual prototyping platform and highlights the interest of integrating energetic aspects in allmodelling stages. For example, this approach enables to quantify the system and components’efficiency, and therefore to optimise earlier in the process the energy consumption of a technicalsolution. Secondly, the problematic of the “Proper Model” has been addressed. After the study ofthe model reduction methodologies, we decide to develop PEMRA in order to compensate forlimitations of the MORA methodology, introduced by Louca et al. in 1997. The previous powerand energy variables are then used to compute two new model reduction criteria, in order toobtain a simpler and more accurate reduced model than with MORA methodology. Finally, weshow that a well-defined excitation signal and a new adapted temporal validation criterion willlead, with this innovative energy- and frequency-based approach, to a better suited reducedmodel.
