Experimental modelling and estimation of time varying thermal sources

Abstract : This paper shows an experimental design where two steps are carried out: (i) the identification of a low order state representation through temperature evolutions corresponding to step responses of a system, (ii) the use of this model to solve an inverse heat conduction problem (IHCP) consisting in the estimation of several strength variations generated by heat sources from time-varying temperature evolutions. Experiments are realized on a 3D heat conductive system (a thick stainless steel tube) in which are set four heat sources, a fifth thermal strength consists in an applied flux boundary condition. After the model identification, a sequential method is used for the resolution of the IHCP: from temperature measurements, the evolutions of the five strengths are identified and compared to the electrical measurements
