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.

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.
