Réduction de modèles thermiques par amalgame modal

Abstract : A complete method (the amalgam method) for reducing state models of linear thermal systems without mass transfer is presented here. We apply the approach to thermal problems. The idea set to work is based on partitioning the model state space into some orthogonal subspaces. The dynamic behavior of each subspace is then approximated by only one pseudo-eigen function. The reduced model obtained with aforementioned method is shown to be optimal with respect to significant error measure. The algorithm runtime is short. Several examples are presented, for which the amalgam method is compared with other approachs.
