The technique of model validation is applied to a thrust-vectored
ducted fan engine experiment at Caltech. Model validation is used to
determine if the nominal model plus an uncertainty structure is able
to account for data generated by the physical system. The uncertainty
structure is the one used when designing H_\inf controllers for the
ducted fan. Additionally, two models are compared using model
validation to see which one is better. The results indicate that the
present uncertainty structure is inadequate to account for some of
the behavior of the ducted fan, and that one of the models is noticeably
better than the other
