Finite-time tracking control for autonomous underwater vehicles: An impulsive communication scheme

open access: yesAdvances in Mechanical Engineering, 2017
This article investigates the finite-time dynamical tracking for autonomous underwater vehicles by introducing an impulsive communication scheme. More precisely, the communication of the autonomous underwater vehicles is conducted by the prescribed ...

Optimized Environment Exploration for Autonomous Underwater Vehicles [PDF]

open access: yes2018 IEEE International Conference on Robotics and Automation (ICRA), 2018
Achieving full autonomous robotic environment exploration in the underwater domain is very challenging, mainly due to noisy acoustic sensors, high localization error, control disturbances of the water and lack of accurate un- derwater maps. In this work we present a robotic exploration algorithm for underwater vehicles that does not rely on prior ...

Risk Analysis for Autonomous Underwater Vehicle Operations in Extreme Environments [PDF]

open access: yes, 2010
Autonomous underwater vehicles (AUVs) are used increasingly to explore hazardous marine environments. Risk assessment for such complex systems is based on subjective judgment and expert knowledge as much as on hard statistics.

Tracking multiple Autonomous Underwater Vehicles

open access: yesAutonomous Robots, 2018
In this paper we present a novel method for the acoustic tracking of multiple Autonomous Underwater Vehicles. While the problem of tracking a single moving vehicle has been addressed in the literature, tracking multiple vehicles is a problem that has been overlooked, mostly due to the inherent difficulties on data association with traditional acoustic ...

Tracking Control Based on GPS Intelligent Buoy System for an Autonomous Underwater Vehicles Under Measurement Noise and Measurement Delay

open access: yesInternational Journal of Computational Intelligence Systems, 2023
This paper deals with the real-time tracking control problem for an autonomous underwater vehicle based on an acoustic-based positioning method, i.e., the so-called GPS intelligent buoy system, which causes inevitable measurement delay.

Nonlinear H∞ Optimal Control Scheme for an Underwater Vehicle with Regional Function Formulation [PDF]

open access: yes, 2013
A conventional region control technique cannot meet the demands for an accurate tracking performance in view of its inability to accommodate highly nonlinear system dynamics, imprecise hydrodynamic coefficients, and external disturbances.
