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.

A New Strategy for Combining Nonlinear Kalman Filters With Smooth Variable Structure Filters

open access: yesIEEE Access, 2023
Bayesian filters exemplified by the celebrated Kalman Filter (KF), and its non-linear variants rely on a fairly accurate state-space model of the system under study.

Multiplicative Kalman filtering [PDF]

open access: yesTEST, 2010
We study a non-linear hidden Markov model, where the process of interest is the absolute value of a discretely observed Ornstein-Uhlenbeck diffusion, which is observed after a multiplicative perturbation. We obtain explicit formulae for the recursive relations which link the relevant conditional distributions.

Quantitative verification of Kalman filters [PDF]

open access: yes, 2021
Kalman filters are widely used for estimating the state of a system based on noisy or inaccurate sensor readings, for example in the control and navigation of vehicles or robots. However, numerical instability or modelling errors may lead to divergenceof

The New Trend of State Estimation: From Model-Driven to Hybrid-Driven Methods

open access: yesSensors, 2021
State estimation is widely used in various automated systems, including IoT systems, unmanned systems, robots, etc. In traditional state estimation, measurement data are instantaneous and processed in real time.

Friction coefficient estimation using an unscented Kalman filter [PDF]

open access: yes, 2014
The friction coefficient between a railway wheel and rail surface is a crucial factor in maintaining high acceleration and braking performance of railway vehicles; therefore, monitoring this friction coefficient is important.

Global Systems for Mobile Position Tracking Using Kalman and Lainiotis Filters

open access: yesThe Scientific World Journal, 2014
We present two time invariant models for Global Systems for Mobile (GSM) position tracking, which describe the movement in x-axis and y-axis simultaneously or separately.

Non-Linear Filtering for Precise Point Positioning GPS/INS integration [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
This research investigates the performance of non-linear estimation filtering for GPS-PPP/MEMS-based inertial system. Although integrated GPS/INS system involves nonlinear motion state and measurement models, the most common estimation filter employed ...

Application of fractional sensor fusion algorithms for inertial mems sensing

open access: yesMathematical Modelling and Analysis, 2009
The work presents an extension of the conventional Kalman filtering concept for systems of fractional order (FOS). Modifications are introduced using the Grünwald‐Letnikov (GL) definition of the fractional derivative (FD) and corresponding truncation of ...

Comparisons of nonlinear estimators for wastewater treatment plants

open access: yes, 2012
This paper deals with five existing nonlinear estimators (filters), which include Extended Kalman Filter (EKF), Extended H-infinity Filter (EHF), State Dependent Filter (SDF), State Dependent H-Infinity Filter (SDHF) and Unscented Kalman Filter (UKF ...
