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.

The concept of structural health monitoring (SHM) of civil infrastructure has evolved rapidly with the incorporation of artificial intelligence (AI). Although available literature mainly focuses on supervised and unsupervised learning to detect and classify damages, both are inherently limited in addressing sequential decision‐making, optimization of ...

Recently, UAVs/drones and their cooperative intelligent swarms have been used more frequently for structural assessment of critical infrastructure (i.e., bridges and wind turbines). Their remote sensing, monitoring, cooperation and communication capabilities facilitate and enhance the inspection process.

ABSTRACT This paper investigates the distributed prescribed‐time formation tracking problem for uncertain multiple six‐degree‐of‐freedom underactuated underwater vehicles operating in dynamic state and input‐triggered environments. A critical challenge lies in addressing the nondifferentiability of event‐triggered state variables during recursive ...

Development of a Cost-Effective UUV Localisation System Integrable with Aquaculture Infrastructure
In many aquaculture farms, Unmanned Underwater Vehicles (UUVs) are being deployed to perform dangerous and time-consuming repetitive tasks (e.g., fish net-pen visual inspection) on behalf of or in collaboration with farm operators.

单只水下机器人导航方法存在着各自的缺陷,无法满足低成本UUV群的作业需要。建立由一只具有高精度自主导航能力的主UUV和多只由低成本导航传感器的随从UUV组成的一主多从式UUV群,研究随从UUV导航方法。与前人的极坐标化方法不同,在直角坐标系下对随从UUV导航系统进行了能观性证明。随从UUV通过测距传感器测量自身到主UUV的距离,采用EKF算法进行位置估计,给出了机动航行方案 ...

Abstract This paper studies a formation control problem with distance constraints for nonlinear agents with uncertainties. Controlling an edge is assigned to only one of its incident agents. Directed graph theory is used to model the desired formation topology.

Optimal UUV Trajectories for Bearings-only Tracking System
在主从式UUVs(Unmanned Underwater Vehicles)系统中,从UUV仅携带被动传感器测得杂波环境下的主UUV方位角信息,通过自主优化其运动轨迹以达到尽快实现与主UUV汇合的目的。分析对比不同的观测载体机动轨迹对仅方位角系统TMA(Target Motion Analysis)精度的影响后,充分考虑到本课题从UUV速度小于主UUV速度这一特殊情况,提出了一种适用于工程应用的基于动态距离最短的轨迹优化方法并且借鉴其它载体航路跟踪模式设计从UUV跟踪轨迹的整体过程 ...
