Dynamics of an Autonomous Underwater Vehicle (AUV) towing another AUV

2023
This thesis studies the motion of an autonomous underwater vehicle towing another autonomous underwater vehicle which is a large as it is. The towed vehicle cannot be assumed to be just a mass attached to the towing vehicle. There is an interaction between the two vehicle.

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.

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.

Navigation of an Autonomous Underwater Vehicle(AUV) Using Robust SLAM

2006 IEEE International Conference on Control Applications, 2006
This paper will present a robust extended Kalman filter (REKF) applied to the navigation of an autonomous underwater vehicle (AUV) using robust Simultaneous Localization and Mapping (SLAM) techniques. Conventional Kalman Filter methods suffer from the assumption of Gaussian noise statistics, which often lead to failures when these assumptions do not ...

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)
