GA-based path planning for multiple AUVs

International Journal of Control, 2007
In this paper, the genetic algorithm (GA), which is a simulation of Darwinian evolution and an efficient way for large-scale optimization subject to non-linear constraints, is applied to find economical and safe routes for a swarm of AUVs to revisit an area with waypoints and obstacles which are known a priori.

AUV positioning based on interactive multiple model

OCEANS'10 IEEE SYDNEY, 2010
The research topic of autonomous underwater vehicles (AUVs) has attracted much attention over years since they provide marine researchers easy ways to access the ocean for surveying and site investigation, etc. To accomplish these applications, an AUV has to know its position accurately. Therefore, AUV localization is very important problem.

A general control architecture for multiple AUVs

Proceedings of Symposium on Autonomous Underwater Vehicle Technology, 2002
This paper presents a conceptual architecture for the control of multiple autonomous underwater vehicles based on the concept of generalized vehicle. The design of this architecture was driven by requirements extracted from the analysis of operational scenarios involving the operation of multiple vehicles and embodies an extension of the dynamically ...

Coordinated path following for multiple underactuated AUVs

OCEANS 2008 - MTS/IEEE Kobe Techno-Ocean, 2008
This paper addresses the problem of coordinated path following whereby multiple underactuated marine crafts are required to follow a prescribed paths while keeping a desired inter-vehicle formation pattern. We show how Lyapunov- based techniques and graph theory can be brought together to yield a decentralized control structure where the dynamics of ...

A Leader-Follower Algorithm for Multiple AUV Formations

2004 IEEE/OES Autonomous Underwater Vehicles (IEEE Cat. No.04CH37578), 2004
In the future, it may be possible to employ large numbers of autonomous marine vehicles to perform tedious and dangerous tasks, such as minesweeping. Hypothetically, groups of vehicles may leverage their numbers by cooperating. A fundamental form of cooperation is to perform tasks while maintaining a geometric formation. The formation behavior can then

Simulation of multiple AUVs underwater wireless recharging

2013 MTS/IEEE OCEANS - Bergen, 2013
Autonomous underwater vehicle (AUV) has become a main tool for underwater exploration and research. The mission capability of AUV is often limited by its on-board energy source, and it is usually the most limiting factor on activity of AUVs. The way of recharging AUVs costs a lot of time at present.

A network protocol for multiple AUV localization

Oceans '02 MTS/IEEE, 2003
With maturing of AUV technology and underwater acoustic modem technology, networks of AUVs have come into the focus of research on future systems for ocean observation and monitoring. In this paper, we propose a networking algorithm for communication within a group of AUVs deployed on a cooperative mission in an area covering several square kilometers.

Market based framework for multiple AUVs cooperation

Journal of Marine Science and Application, 2005
A “Market” based framework for multiple AUVs team is introduced in this paper. It is a distributed meta-level task allocation framework. The formulation and the basic concepts of the “Market” such as “goods” and “price” are discussed first, then the basic algorithm of the “auction”.

Coordinated maneuver for gradient search using multiple AUVs

Oceans 2003. Celebrating the Past ... Teaming Toward the Future (IEEE Cat. No.03CH37492), 2003
The coordinated use of multiple Autonomous Underwater Vehicles can provide important advantages for oceanographic missions. One important mission application scenario can be the search of underwater plumes such as sources of freshwater of hydrothermal vents.

Distributed adaptive consensus tracking control for multiple AUVs

2017 Seventh International Conference on Information Science and Technology (ICIST), 2017
This paper is concerned with the adaptive consensus tracking problem for multi-AUV (autonomous underwater vehicle) systems with uncertain parameters. A neutral network-based command filtered backstepping control scheme is developed, which can guarantee the consensus tracking error of position converging to the desired neighborhood.
