Acoustic Tracking of Autonomous Underwater Vehicles by a Set-membership Approach
نویسندگان
چکیده
An algorithm is presented for tracking of Autonomous Underwater Vehicles (AUVs) from acoustic time-of-flight measurements received by a field of surface floating buoys. The algorithm assumes that measurements and AUV dynamics uncertainties are unknown but bounded, with known bounds, and produces as output the set of admissible AUV positions. The algorithm has been validated by simulation in which uncertainty models have been obtained from field data at sea. Copyright © 2002 IFAC

Adaptive Robust Control for Trajectory Tracking of Autonomous underwater Vehicles on Horizontal Plane
This manuscript addresses trajectory tracking problem of autonomous underwater vehicles (AUVs) on the horizontal plane. Adaptive sliding mode control is employed in order to achieve a robust behavior against some uncertainty and ocean current disturbances, assuming that disturbance and its derivative are bounded by unknown boundary levels. The proposed approach is based on a dual layer adaptive...
متن کاملAn Approach for Operation Depth Reduction of an Underwater Glider Propelled by Ocean Thermal Energy
The underwater Gliders are a kind of autonomous vehicles that have a special role in ocean surveys which demand continuous monitoring and long endurance. Because of low energy consumption and long endurance, these vehicles are favorite for these missions. Among this, a type of gliders can harvest ocean thermal energy, causing significant endurance increase. These vehicles need at least 680 mete...

In this paper, kinematic and dynamic equations of a 6-DOF (Degrees Of Freedom) autonomous underwater vehicle (6-DOF AUV) are introduced and described completely. By developing the nonsingular terminal sliding mode control method, three separate groups of control inputs are proposed for the autonomous underwater vehicle subjected to uncertainties including parametric uncertainties, unmodeled dyn...
متن کاملAutonomous Underwater Vehicle Hull Geometry Optimization Using a Multi-objective Algorithm Approach
Abstarct In this paper, a new approach to optimize an Autonomous Underwater Vehicle (AUV) hull geometry is presented. Using this methode, the nose and tail of an underwater vehicle are designed, such that their length constraints due to the arrangement of different components in the AUV body are properly addressed. In the current study, an optimal design for the body profile of a torpedo-shaped...
متن کاملCoordinated Tracking of an Acoustic Signal by a Team of Autonomous Underwater Vehicles
We describe an approach to decentralized control and distributed data fusion that enables a team of autonomous underwater vehicles to cooperatively and autonomously localize and track a source of acoustic noise, and we report on field experiments that demonstrate the efficacy of our approach. A principal challenge of subsea coordination is the the extremely low-bandwidth acoustic communication ...
