SUBSTRUCTURED MODELING OF LINEAR THERMAL SYSTEMS: THE MODEL SYNTHESIS

Abstract

A general and systematic procedure for generating thermal state space models is presented. It allows one to build models of complex thermal systems by assembling elementary models which caneachbe generated with specific methods or tools. A size reduction procedure may be applied on every elementary model. This method is particularly useful when modeling large systems requiring detailed meshing, as it allows one to distribute the calculation effort along a process which does not require handling the whole global, nonreduced problem. This approach is coherent with a reusability strategy in which models of elementary parts are stored in libraries.
