Development of Algal Bloom Removal System Using Unmanned Aerial Vehicle and Surface Vehicle

IEEE Access, 2017
Recently, owing to changes in weather conditions, cyanobacterial blooms, also known as harmful algal blooms (HABs), have caused serious damage to the ecosystems of rivers and lakes by producing cyanotoxins.

Dual‐Layer Model Predictive Control for Multi‐Vessels Formation With Predefined‐Time and Collision‐Free Strategy

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
A dual‐layer formation control with a predefined‐time and collision‐free strategy is studied in this work. Its upper layer utilises performance indicators, including tracking objectives to meet tracking control requirements. The lower layer tracks those trajectories to save computational and communication resources.

A New Fault Detection Method for Systems With Uncertainty Under Denial‐of‐Service Attack

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
Probabilistic parameter models are first established for describing model uncertainties, disturbances and faults in systems under denial‐of‐service attack. A novel approach is proposed for designing the switched fault detection filter for uncertain systems utilizing a randomized algorithm.

Variable-Resolution Virtual Maps for Autonomous Exploration with Unmanned Surface Vehicles (USVs)

CoRR
Autonomous exploration by unmanned surface vehicles (USVs) in near-shore waters requires reliable localisation and consistent mapping over extended areas, but this is challenged by GNSS degradation, environment-induced localisation uncertainty, and limited on-board computation.

Study on key technologies for air–water surface collaboration of observation unmanned aircraft vehicle

Electronics Letters, Volume 61, Issue 1, January/December 2025.
To address the issues of short flight duration and the inability to carry high‐computation resources in small observation unmanned aerial vehicles (UAVs) due to limited energy and payload capacities, a deployment framework is proposed for an air–water surface collaborative observation system based on energy replenishment and computation offloading.

PBM‐YOLO: A Performance Balanced Floating Garbage Detection Model for Water Surface Environments

IET Image Processing, Volume 19, Issue 1, January/December 2025.
We propose a lightweight detection model, PBM‐YOLO, for floating garbage detection on water surfaces. Based on YOLOv8n, the model introduces a feature extraction module (FSEM) that integrates frequency and spatial information to enhance object representation.
