Number : Title : Data Assimilation with an Extended Kalman Filter for

Model assimilation of data strives to determine optimally the state of an evolving physical system from a limited number of observations. The present study represents the first attempt of applying the extended Kalman filter (EKF) method of data assimilation to shock-wave dynamics induced by a high-speed impact. EKF solves the full nonlinear state evolution and estimates its associated error-cov...

Balanced multivariate model errors of an intermediate coupled model for ensemble Kalman filter data assimilation

[1] The ensemble Kalman filter (EnKF) depends on a set of ensemble forecasts to calculate the background error covariances. Without model error perturbations and the inflation of forecast ensembles, the spread of the ensemble forecasts can collapse rapidly. There are several ways to generate model perturbations, i.e., perturbations in model parameters/parameterizations, perturbations in the for...

Identification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...
