Statistical Identifi cation. Observability and Identifi ability of Dynamical Systems, Algorithmic Feasibility of Adaptive Filtering |
V.I. Kuznetsov
The questions that determine the possibility of the practical applicability of adaptive nonlinear fi ltering under the joint estimation
of states and parameters identifi cation of nonlinear non-stationary stochastic dynamical systems close on the feasibility conditions of
observability and identifi ability, as well as the algorithmic feasibility of adaptive fi ltering. The possibility of using the local-rank test observability for nonlinear systems with time-varying parameters at each time point of receipt of measurement data based on the infi nitesimal
transformations of the phase space of a nonlinear dynamical system in the linear space of differential 1-forms. Substantiated conditions
algorithmic feasibility of adaptive nonlinear fi ltering, including the operations of matrix inversion when determining the gain matrix of the nonlinear fi lter and a posteriori estimation of the covariance matrix perturbations in the equations of the model states.
Keywords: identifi ability; model; observability; estimate; parameter; condition; fi ltering.
