Résumé : |
Observers are proposed as a solution algorithm for the inverse heat conduction problems (IHCP) of reconstructing a time-dependent surface heat flux at the boundary of a linear heat conductor. Solving the IHCP is viewed as a filter design problem in which the reconstructed heat flux is obtained by lowpass-filtering of the true heat flux. It is demonstrated that observers yield a better tradeoff between the deterministic bias and the sensitivity to measurement errors and lead to smaller-size computational problems than other solution approaches. |
