Representing Uncertainty
Parametric uncertainty. Here the structure of the model (including the order) is known, but some of the parameters are uncertain.

2. Neglected and unmodelled dynamics uncertainty (Unstructed uncertainty). Here the model is in error because of missing dynamics, usually at high frequencies, either through deliberate neglect or because of a lack of understanding of the physical process. Any model of a real system will contain this source of uncertainty.
