Robust Beamforming for ISAC Systems via Probability of Detection Optimisation
Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...

An Iterative Method for Moving Target Localization Using TDOA and FDOA Measurements
IEEE Access, 2018 For moving targets localization, incorporating frequency-difference-of-arrival (FDOA) measurements in the commonly used time-difference-of-arrival (TDOA) positioning systems will improve performance.

A Voronoi Diagram‐Based Approach for AC Optimal Power Flow
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

Range‐Free Localisation for Monostatic Passive Radar Employing Multi‐Narrowband Illuminators
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Range‐free localisation is considered for monostatic passive radar with multiple narrowband illuminators under unreliable time‐delay (range) measurements. Doppler/DOA (and optional Doppler‐rate) are fused in an ML framework, where velocity is iteratively updated to reduce the original 6‐D optimisation to a 3‐D position search.

IET Signal Processing, Volume 2026, Issue 1, 2026.Formation control of multi‐autonomous underwater vehicle (AUV) systems is essential for collaborative ocean tasks such as environmental monitoring and resource exploration, but it is hindered by challenges like limited flexibility in formation transformation, model uncertainties, and unknown ocean current disturbances.

IET Smart Grid, Volume 9, Issue 1, January/December 2026.The high penetration of renewable energy intensifies power system stochasticity, leading to frequent static security violations that conventional offline and manual methods cannot address in a timely manner. This paper proposes an interpretable machine learning‐based high‐frequency static security adjustment method, which integrates a multitask XGBoost

Optimal Control for a Class of Chaotic Systems
Journal of Applied Mathematics, 2012 This paper proposes the optimal control methods for a class of chaotic systems via state feedback. By converting the chaotic systems to the form of uncertain piecewise linear systems, we can obtain the optimal controller minimizing the upper bound on ...

RIS‐Assisted Beam Selection System Using CNN for 6G Wireless Communications
Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.Reconfigurable intelligent surfaces (RISs) are a promising technology for improving mobile communication performance due to their ability to shape the propagation environment. In this paper, an RIS‐assisted beamforming framework is proposed with low computational complexity.
