Towards building a safety case for Marine Unmanned Surface Vehicles: a Bayesian perspective [PDF]
Marine Unmanned Surface Vehicles (MUSVs) are essential platforms for persistent and adaptable ocean monitoring and sampling. In order to operate these platforms in coastal areas or near oil and gas waters the MUSVs must meet statutorily and industry ...

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.

In this work we propose a solution to the Unmanned Surface Vessels (USV) path-following problem by suggesting an improved model predictive control (MPC) based on global course constraint (GCC) and event-triggered mechanism (ETM).

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
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.

Autonomous boat dynamics: how far away is simulation from the high sea? [PDF]
The study demonstrates the process of implementing a 3-degrees-of-freedom surge-sway-yaw boat dynamic model in a numeric simulation environment. Estimated environmental disturbance force introduced in the simulation provides a scope for determining boat ...

Parameter optimization of unmanned surface vessel propulsion motor based on BAS-PSO
Despite advances in modern control theory and artificial intelligence technology, current methods for tuning proportional-integral-derivative (PID) controller parameters based on the traditional particle swarm optimization (PSO) algorithm do not meet the

1. An adaptive speed control method is proposed to execute the ship formation trajectory tracking task more efficiently and safely while entering port with tidal elevation variations. 2. A distributed ship formation controller based on the leader‒follower structure is designed to govern the coordinated motion of formation members more flexibly. 3.
