Local Identifiability and Observability of Nonlinear Differential-Algebraic Equations, Report no. LiTH-ISY-R-2711
نویسنده
چکیده
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 differentialalgebraic 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.

Using DAE Solvers to Examine Local Identifiability for Linear and Nonlinear Systems, Report no. LiTH-ISY-R-2712
If a model structure is not identifiable, then it is not possible to uniquely identify its parameters from measured data. This contribution describes how solvers for differential-algebraic equations (DAE) can be used to examine if a model structure is locally identifiable. The procedure can be applied to both linear and nonlinear systems. If a model structure is not identifiable, it is also pos...
متن کاملOn Identifiability of Object-Oriented Models, Report no. LiTH-ISY-R-2710
When estimating unknown parameters, it is important that the model is identifiable so that the parameters can be estimated uniquely. For nonlinear differentialalgebraic 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 objectoriented ...
متن کاملDescriptor Systems and Control Theory, Report no. LiTH-ISY-R-2688
This report is a brief survey over different concepts and methods concerning singular systems. Singular system is also called differential algebraic equations (DAE) since a DAE model may involve both differential and algebraic equations. There is an growing interest in DAE systems much depending on the increased usage of object oriented modeling languages, like Modelica, in the modeling of dyna...
متن کاملGlobal Identifiability of Complex Models, Constructed from Simple Submodels, Report no. LiTH-ISY-R-2783
It is a typical situation in modern modeling that a total model is built up from simpler submodels, or modules, for example residing in a model library. The total model could be quite complex, while the modules are well understood and analysed. A procedure to decide global parameter identi ability for such a collection of model equations of di erential-algebraic nature is suggested. It is shown...
متن کاملA relaxation of the strangeness index, Report no. LiTH-ISY-R-2932
A new index closely related to the strangeness index of a differential-algebraic equation is presented. Basic properties of the strangeness index are shown to be valid also for the new index. The definition of the new index is conceptually simpler than that of the strangeness index, hence making it potentially better suited for both practical applications and theoretical developments.
