Adaptive Robust Finite-Time Nonlinear Control of a Typical Autonomous Underwater Vehicle With Saturated Inputs and Uncertainties

IEEE/ASME transactions on mechatronics, 2021
The problem of finite-time path following control for a typical 6-DOF (degree of freedom) autonomous underwater vehicle (AUV) subjected to parametric and modeling uncertainties, disturbances and unknown saturation nonlinearities is studied and discussed ...

From autonomous underwater vehicles (AUVs) to supervised underwater vehicles (SUVs)

Oceans '97. MTS/IEEE Conference Proceedings, 2002
The past fifteen years have seen the development of a new family of unmanned underwater vehicles without umbilical. Initially, those vehicles were operated in the direct vicinity of the mother-ship. With the increase in range and reliability, users are now willing to operate without support vessels.

Passive Inverted Ultra-Short Baseline Positioning for a Disc-Shaped Autonomous Underwater Vehicle: Design and Field Experiments

IEEE Robotics and Automation Letters, 2022
Underwater positioning is critical to autonomous underwater vehicles (AUVs) for navigation and geo-referencing. The rapid attenuation of the electromagnetic wave in the underwater environment prevents the use of traditional positioning methods such as ...

Design of Line-of-Sight Guidance Law and a Constrained Optimal Controller for an Autonomous Underwater Vehicle

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2021
A line-of-sight (LOS) guidance law with an explicit model predictive control (MPC) is proposed for an underactuated autonomous underwater vehicle (AUV). The derived LOS law is based on quaternion angles thus avoids the problem of singularity inherited in

Robust control of Autonomous Underwater Vehicles (AUVs)

2008 Canadian Conference on Electrical and Computer Engineering, 2008
This paper presents a robust nonlinear method for controlling depth and head of Autonomous Underwater Vehicles. The control of autonomous underwater vehicles (AUV) presents a number of unique and formidable challenges. AUV dynamic is highly nonlinear, coupled, time varying and subject to hydrodynamic uncertainties and external disturbances.

Path Planning for Autonomous Underwater Vehicle Based on Artificial Potential Field and Modified RRT

2021 International Conference on Computer, Control and Robotics (ICCCR), 2021
Autonomous underwater vehicle(AUV) plays an important role in modern aquaculture. For example, it can be applied to monitor water quality as well as the fish biomass. In these activities, path planning is significant for AUV.

Cable Route Surveys Utilizing Autonomous Underwater Vehicles (AUVs)

Marine Technology Society Journal, 2000
Detailed geophysical surveys are required in both deep and shallow water to avoid potential hazards and to provide for the installation and safety of fiber optic telecommunication cables. Unfortunately, data obtained in potential burial zones with existing technology are slow and often data accuracy may be questionable.

Energy systems for FAU AUVs [autonomous underwater vehicles]

Proceedings of the 2002 Workshop on Autonomous Underwater Vehicles, 2002., 2003
The AUV research program at Florida Atlantic University (USA) has focused its design efforts on battery powered AUVs, developing both the battery packs and power distribution systems that provide a robust energy system for the AUV. This paper focuses on the development of our energy systems on their 3 AUVs (Ocean Voyager II, Ocean Explorer and Morpheus)
