Indoor Positioning Algorithm Based on Maximum Correntropy Unscented Information Filter

ISPRS International Journal of Geo-Information, 2021
In view of the fact that indoor positioning systems are usually affected by non-Gaussian noise in complex indoor environments, this paper tests the data in the actual scene and analyzes the distribution characteristics of noise, and proposes a new indoor

Secure Dynamic State Estimation of WECS‐Based Networked Microgrids Against Historical Measurement Triggered DoS Attacks

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This work addresses the issue of rejection delay due to DoS attacks triggered by historical measurements during the transmission of a large amount of measurement data in WECS‐based networked microgrids. We propose a novel robust SRCKF method, designated as MCC‐SRCKF, which incorporates MCC into the SRCKF structure of DSE.

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
To reduce the affection of outliers caused by heavy‐tailed noise, the noise model is constructed by the Student's T distribution rather than the Gaussian distribution, and the related probability density functions (PDF) are adaptively modelled as student's T PDFs with different DoF parameters.

Robust rigid registration via maximum correntropy criterion: a novel approach

Scientific Reports
Point set registration is essential for computer vision, pattern recognition and intelligent robotics. Existing registration methods exhibit limited robustness against non-Gaussian noise, outliers and incomplete point clouds in complex engineering ...

Passive Target Motion Analysis With Own‐Ship Location Uncertainty in the Presence of Non‐Gaussian Sensor Noise

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This work explores underwater TMA by incorporating time delay and Doppler frequency measurements along with angle data, eliminating the need for own‐ship manoeuvre and improving estimation accuracy in presence of non‐Gaussian sensor noise. Furthermore, since the own‐ship's position is inherently uncertain due to navigation errors, this work addresses ...

ℓ1${\ell }_1$ norm‐based recursive estimation for non‐linear systems with non‐Gaussian noises

IET Control Theory &Applications, Volume 18, Issue 11, Page 1424-1434, July 2024.
This study presents the state estimation problem of discrete‐time nonlinear stochastic system with non‐Gaussian noise. To further improve estimation accuracy, a recursive nonlinear smoother is put forward on the basis of minimizing l1 norm of model errors.

Evaluation method for electromagnetic interference complexity of high voltage switch based on feature extraction and GCC‐GRU network

High Voltage, Volume 9, Issue 3, Page 749-761, June 2024.
Abstract When some new‐type sensors are subjected electromagnetic interference (EMI), the traditional standard can no longer serve as the guidance for their EMI protection. Therefore, it is necessary to evaluate the complexity of the new sensing equipment's suffering from electromagnetic interference.

Robust Nonlinear GNSS Navigation Under Heavy-Tailed Measurement Noise Using a Cauchy-Kernel Correntropy Extended Kalman Filter

IEEE Access
In urban canyon environments, the performance of global navigation satellite systems (GNSS) is severely degraded by multipath propagation, signal occlusion, and non-Gaussian measurement noise.

Robust localisation methods based on modified skipped filter weighted least squares algorithm

IET Radar, Sonar &Navigation, Volume 18, Issue 6, Page 825-837, June 2024.
Robust localisation techniques that utilise distance observations to determine the location are focused upon. The modified skipped filter WLS methods are proposed to reduce the squared estimation bias of transformed distance estimate. Abstract Robust localisation techniques that utilise distance observations to determine the location are focused upon ...
