Abstract

When system identification methodologies are used to interpret measurement datataken from structures, uncertainty dependencies are in many cases unknown due tomodel simplifications and omissions. This paper presents how error-domain model falsificationreveals properties of a structure when uncertainty dependencies are unknownand how incorrect assumptions regarding model-class adequacy are detected. An illustrativeexample is used to compare results with those from a residual minimizationtechnique and Bayesian inference. Error-domain model falsification correctly identifiesparameter values in situations where there are systematic errors, and can detect thepresence of unrecognized systematic errors.
