Active Disturbance Rejection Control of Underwater Vehicle with Omnidirectional Control

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
This paper focuses on the omnidirectional drive characteristics and autonomous control of the underwater saucer glider under the condition of underactuated and multiconstraints. Firstly, the dynamic model of the underwater saucer glider is established, and the underactuated control characteristics and the plane biaxial symmetry structure ...

Grid-based GA path planning with improved cost function for an over-actuated hover-capable AUV [PDF]

, 2014
For an AUV to perform a long-range mission with its maximum endurance, its energy consumption during transit must be kept to a minimum. This paper presents an improved cost function for a grid-based genetic algorithm (GA) path planning in 2D static ...

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

, 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.

A Markov Chain state transition approach to establishing critical phases for AUV reliability [PDF]

, 2011
The deployment of complex autonomous underwater platforms for marine science comprises a series of sequential steps. Each step is critical to the success of the mission. In this paper we present a state transition approach, in the form of a Markov chain,

A 3D reactive collision avoidance algorithm for underactuated underwater vehicles

Journal of Field Robotics, Volume 37, Issue 6, Page 1094-1122, September 2020., 2020
Abstract Avoiding collisions is an essential goal of the control system of autonomous vehicles. This paper presents a reactive algorithm for avoiding obstacles in a three‐dimensional space, and shows how the algorithm can be applied to an underactuated underwater vehicle. The algorithm is based on maintaining a constant avoidance angle to the obstacle,

Sustainable Observations of the AMOC: Methodology and Technology

Reviews of Geophysics, Volume 58, Issue 1, March 2020., 2020
Abstract The Atlantic Meridional Overturning Circulation (AMOC) is a key mechanism of heat, freshwater, and carbon redistribution in the climate system. The precept that the AMOC has changed abruptly in the past, notably during and at the end of the last ice age, and that it is “very likely” to weaken in the coming century due to anthropogenic climate ...

Learning‐based tracking control of AUV: Mixed policy improvement and game‐based disturbance rejection

CAAI Transactions on Intelligence Technology, Volume 10, Issue 2, Page 510-528, April 2025.
Abstract A mixed adaptive dynamic programming (ADP) scheme based on zero‐sum game theory is developed to address optimal control problems of autonomous underwater vehicle (AUV) systems subject to disturbances and safe constraints. By combining prior dynamic knowledge and actual sampled data, the proposed approach effectively mitigates the defect caused
