Unscented Kalman filter for spacecraft attitude estimation using modified Rodrigues parameters and real data
(2016-10-01)
In this paper, a sigma-point Kalman filter formulation for attitude estimation is derived using the modified Rodrigues parameters and real data of attitude sensors. The unscented Kalman filter algorithm is used for attitude ...
A Kalman-filtering-based Approach for Improving Terrain Mapping in off-road Autonomous Vehicles
(Springer, 2015)
The generation of accurate terrain maps while navigating over off-road, irregular terrains is a complex challenge, due to the difficulties in the estimation of the pose of the laser rangefinders, which is required for the ...
A Posterior Ensemble Kalman Filter Based On A Modified Cholesky Decomposition
(Elsevier, 2017-06-12)
In this paper, we propose a posterior ensemble Kalman filter (EnKF) based on a modified Cholesky decomposition. The main idea behind our approach is to estimate the moments of the analysis distribution based on an ensemble ...
Filtragem estocástica não linear aplicada ao problema de monitoramento e estimativa de enchentes

(A Comparative Analysis. In the Annual Conference of the Prognostics and Health Management Society 2015A Comparative Analysis. In the Annual Conference of the Prognostics and Health Management Society 2015, 2015-08-24)
Battery energy systems are currently one of the most common power sources found in mobile electromechanical devices. In all these equipment, assuring the autonomy of the system requires to determine the battery state-of-charge ...
Fast and low power integrated circuit for impulsive sound localisation using Kalman filter approach
(Institution of Engineering and Technology, 2010-04)
A fast low power time delay estimator for the localisation of impulsive sounds is shown. The system is based on a simplified Kalman filter structure and is implemented on a 0.5 m standard CMOS architecture. Tests show that ...
