“…In the perfect-deterministic model setting, the asymptotic filter performance can likewise be understood principally in terms of the dynamical properties of the model. Particularly, the statistics are determined by the ability of the filter to correct for the dynamical instabilities of perturbations along the truth-twin trajectory with respect to the sensitivity of the filter to its observations Frank and Zhuk, 2018;Maclean and Van Vleck, 2019;Tranninger et al, 2019).…”

“…Finally we stress that our design is minimal in that one cannot make use of Lyapunov subspace reduction (e.g. [5], [13]) and restrict the observer's gain corrections just to the stable Lyapunov subspace due to the following fact: all the Lyapunov exponents of the considered dynamical system equal to zero. Nevertheless, unlike [5] we do not require to observe all "unstable directions" instead requiring the uniform complete observability along the observer's trajectory.…”

“…Introduction. In recent years, detectability analysis of complex dynamical systems gained a lot of research attention in different engineering fields [7,22,26,45,47]. Despite the fact that detectability is very well studied for linear time invariant systems [41], the underlying theory and existing detectability conditions are less mature for the time varying and/or nonlinear setting.…”
