Local Identifiability and Observability of Nonlinear Differential-Algebraic Equations
2006 (English)In: Proceedings of the 14th IFAC Symposium on System Identification, 2006, 802-807 p.Conference paper (Refereed)
Identifiability is important to guarantee convergence in system identification applications, and observability is important in applications such as control and diagnosis. In this paper, recent results on analysis of nonlinear differential-algebraic equations are used to derive criteria for local identifiability and local weak observability for such models. The criteria are based on rank tests. Examples show the relationship between the new criteria and standard methods for state-space systems.
