Classical validation methods “accept” or “reject” a model as a valid representation of a plant for
some intended use. However this binary result has several problems as firstly, models are neither good
nor bad but have a certain valid frequency range and secondly the procedure gives no insight into
why the model is not useful or how to improve the model. Moreover within the framework of iterative
identification and control design the model validation issue arises the following requirements: i) Is it
possible to improve an existing model?. ii) How can the model be improved?. iii) How authoritative can
be the designed controller?. These facts question the suitability of traditional model validation schemes
in general and their suitability for iterative control schemes in particular. We present a new validation
procedure that overtakes these problems by performing the model validation frequency dependent. The
validation procedure is then more informative due to its frequency information content. As a result the
same model can be validated for some frequency band and invalidated for a distinct frequency range [-]
