Abstract

The model distortion approach to the external validation of linear and nonlinear dynamic models uses the time histories of model parameter variations needed to ensure that the model output exactly fits experimental data from the real system as a basis for assessing the acceptability or otherwise of a given representation. It must then be established whether the variance of parameter distortions is less than the uncertainty of parameter values in the associated model.If the distortions are all well within acceptable limits the model may be regarded as a suitable representation of the system. This paper describes applications of the distortion approach using both simulated and experimental response data. Problems associated with measurement noise are highlighted in the results.
