Robust Estimation of Optical Phase Varying as a Continuous Resonant Process [PDF]

, 2013
It is well-known that adaptive homodyne estimation of continuously varying optical phase provides superior accuracy in the phase estimate as compared to adaptive or non-adaptive static estimation.

Double‐state chi‐square test based sparse grid quadrature filtering algorithm and its application in integrated navigation

IET Control Theory & Applications, 2023
Aiming to reduce the impact that the measurement uncertainty of nonlinear system brings to filtering accuracy, a novel sparse grid quadrature filter (SGQF) algorithm based on the double‐state chi‐square test is proposed.

INS/GPS Sensor Fusion based on Adaptive Fuzzy EKF with Sensitivity to Disturbances

IET Radar, Sonar & Navigation, 2021
The estimation accuracy of the inertial navigation system integrated with the global positioning system (GPS) through multiple kinds of Kalman filters (KFs) has been widely considered. Since the classical KFs could not overcome environmental disturbances

Robust ensemble filtering and its relation to covariance inflation in the ensemble Kalman filter [PDF]

, 2011
We propose a robust ensemble filtering scheme based on the $H_{\infty}$ filtering theory. The optimal $H_{\infty}$ filter is derived by minimizing the supremum (or maximum) of a predefined cost function, a criterion different from the minimum variance ...

State-of-charge estimation for Lithium-Ion batteries using Kalman filters based on fractional-order models

Connection Science, 2022
The accuracy of state of charge estimation results will directly affect the performance of battery management system. Due to such, we focus in this article on the SOC estimation of Lithium-Ion batteries based on a fractional second-order RC model with ...

An adaptive hybrid filter for practical WiFi-based positioning systems

ICT Express, 2015
This paper proposes an adaptive hybrid filter for WiFi-based indoor positioning systems. The hybrid filter adopts the notion of particle filters within the prediction framework of the basic Kalman filter.

Convergence Analysis of Ensemble Kalman Inversion: The Linear, Noisy Case [PDF]

, 2017
We present an analysis of ensemble Kalman inversion, based on the continuous time limit of the algorithm. The analysis of the dynamical behaviour of the ensemble allows us to establish well-posedness and convergence results for a fixed ensemble size.

Robust Land-Surface Parameterisation for Repeated Topographic Surveys in Dynamic Environments with Adaptive State-Space Models

Remote Sensing
The proliferation of unmanned aerial vehicles has enabled cost-effective topographic surveys to be collected at high frequencies. However, terrain analyses rarely take advantage of the information provided by repeated observations.

A New Approach to Adaptive Signal Processing

, 2015
A unified linear algebraic approach to adaptive signal processing (ASP) is presented. Starting from just Ax=b, key ASP algorithms are derived in a simple, systematic, and integrated manner without requiring any background knowledge to the field ...
