Mixture Kalman Filters

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2000
Summary In treating dynamic systems, sequential Monte Carlo methods use discrete samples to represent a complicated probability distribution and use rejection sampling, importance sampling and weighted resampling to complete the on-line ‘filtering’ task. We propose a special sequential Monte Carlo method, the mixture Kalman filter, which

Application of H∞ Filter on the Angular Rate Matching in the Transfer Alignment

open access: yesDiscrete Dynamics in Nature and Society, 2016
The transfer alignment (TA) scheme is used for the initial alignment of Inertial Navigation System (INS) on dynamical base. The Kalman filter is often used in TA to improve the precision of TA.

Steady state Kalman filter design for cases and deaths prediction of Covid-19 in Greece

open access: yesResults in Physics, 2021
In this work we study the applicability of the steady state Kalman filter in order to predict new cases and deaths of Covid-19. We use the actual observations of new cases and deaths. First, we deal with short term prediction, namely daily prediction. We

Improvement of ECG Signal Noise Removal Using Recursive Kalman Filter [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2011
Nowadays, Kalman filter has been wildly used for solving the problem of real world. Kalman filter is a recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements.

Robust adaptive cubature Kalman filter for tracking manoeuvring target by wireless sensor network under noisy environment

open access: yesIET Radar, Sonar & Navigation, 2023
The existing adaptive Kalman filters for tracking manoeuvring targets by wireless sensor networks can easily lose robustness when both the measurement and process noises are unknown and time‐varying, resulting in large positioning errors.

Robust Kalman Filtering [PDF]

open access: yes, 2000
As already pointed out in Hardle, Klinke, and Muller (2000, Chapter 10), state-space models are very useful and flexible in the sense that various recursive methods for time-dependent situations can be formulated as general solutions of filtering, smoothing and prediction problems in state-space models.
