An important consideration in control system design is that of model uncertainty. If one chooses to fix the nominal model, then in general, the associated description of the uncertainty will necessarily be very conservative. Alternatively, on line model estimation allows the nominal model to be adjusted as the system changes thereby offering the possibility for a less conservative estimate of the associated uncertainty. However this strategy depends on the model estimator having the capacity to provide information on both the nominal model and the associated uncertainty. Most of the existing paradigms for estimation give emphasis to the estimation of the nominal model but do not address the uncertainty issue.
