Adaptive ensemble Kalman filtering of nonlinear systems
A necessary ingredient of an ensemble Kalman filter is covariance inflation [1], used to control filter divergence and compensate for model error. There is an ongoing search for inflation tunings that can be learned adaptively. Early in the development of Kalman filtering, Mehra [2] enabled adaptivity in the context of linear dynamics with white noise model errors by showing how to estimate the...
متن کاملNonlinear Kalman filtering for censored observations
The use of Kalman filtering, as well as its nonlinear extensions, for the estimation of system variables and parameters has played a pivotal role in many fields of scientific inquiry where observations of the system are restricted to a subset of variables. However in the case of censored observations, where measurements of the system beyond a certain detection point are impossible, the estimati...
متن کاملUnscented Kalman filtering for nonlinear structural dynamics
Joint estimation of unknown model parameters and unobserved state componentsfor stochastic, nonlinear dynamic systems is customarily pursued via the extendedKalman filter (EKF). However, in the presence of severe nonlinearities in the equa-tions governing system evolution, the EKF can become unstable and accuracy ofthe estimates gets poor. To improve the results, in this paper w...
متن کاملNonlinear Kalman filtering with semi-parametric Biscay distributions
The problem of nonlinear estimation is reexamined, and a new semi-parametric representation of uncertainty called the Biscay distribution is presented. The Biscay distribution is combined with the extended Kalman filter (EKF) and a new filtering paradigm called the Biscay distribution filter (BDF) is developed. The BDF is provably optimal for linear estimation and generalizes naturally to nonli...
متن کاملCorrection to "nonlinear kalman filtering with semi-parametric biscay distributions"
In the above-mentioned paper, 1 the author found a minor error that only affects " book keeping " within the theory of Biscay distributions. Therefore, (14) and (15) should read In the above-mentioned paper, 1 the author found the following errors. — On p. 1721, the three last lines of Section D must be modified as follows: the process of the joint diagonalization of 1 V 1 and 2 V 2 may give (6...
