On Identifiability of Object-Oriented Models
2006 (English)In: Proceedings of the 14th IFAC Symposium on System Identification, 2006, 820-825 p.Conference paper (Refereed)
When estimating unknown parameters, it is important that the model is identifiable so that the parameters can be estimated uniquely. For nonlinear differential-algebraic equation models with polynomial equations, a differential algebra approach to examine identifiability is available. This approach can be slow, so the present paper describes how this method can be modularized for object-oriented models. A characteristic set of equations is computed for components in model libraries, and stored together with the components. When an object-oriented model is built using such models, identifiability can be examined using the stored equations.
