Underwater gliders control strategies: A review
2015 10th Asian Control Conference (ASCC), 2015Underwater Gliders (UGs) are a type of Autonomous Underwater Vehicle (AUV) that uses buoyancy engines, an energy efficient locomotion, primarily for oceanography. In this paper, control strategies for existing underwater gliders are reviewed. A total of 50 papers indexed by Scopus with keywords control and underwater gliders were reviewed from 1989 to ...

Task allocation approach for underwater gliders in complex underwater missions
2021 4th IEEE International Conference on Industrial Cyber-Physical Systems (ICPS), 2021This paper proposes an Genetic Algorithm(GA)-based task allocation approach for heterogenous underwater gliders in complex underwater search and detection missions. First of all, the mathematical model of the underwater glider task allocation problem is formulated while considering motion characteristics of underwater gliders and different task ...

This chapter discusses the characteristics, design considerations, and performance of autonomous underwater (UW ) gliders. These buoyancy-propelled, winged vehicles can be categorized as: (1) profiling gliders that traverse in bobbing trajectories to collect vertical profiles of ocean properties and (2) cross-country gliders designed for point-to-point

Motion Simulation of an Underwater Glider
2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics, 2015Underwater glider is a new type of autonomous underwater vehicle driven by gravity. In order to study the relationship between the motion parameters and control variable of the underwater glider, solve the fluctuation problem of pitching angle and attack angle in the process of attitude changing, simulation via the software Mat lab is performed based ...

A maneuverable, pneumatic underwater glider
2012 Oceans, 2012A coastal (100 meter depth) underwater glider has been developed to serve as a platform for testing advanced perception, planning, and control algorithms to improve glider efficiency and performance. The glider's buoyancy engine is pneumatically powered, and capable of generating large changes in buoyancy.

Routing strategies for underwater gliders
Deep Sea Research Part II: Topical Studies in Oceanography, 2009Abstract Gliders are autonomous underwater vehicles that achieve long operating range by moving at speeds comparable to those of, or slower than, typical ocean currents. This paper addresses routing gliders to rapidly reach a specified waypoint or to maximize the ability to map a measured field, both in the presence of significant currents. For rapid

The autonomous underwater glider "Spray"
IEEE Journal of Oceanic Engineering, 2001A small (50-kg, 2-m long) underwater vehicle with operating speeds of 20-30 cm/s and ranges up to 6000 km has been developed and field tested. The vehicle is essentially an autonomous profiling float that uses a buoyancy engine to cycle vertically and wings to glide horizontally while moving up and down.

Stability and performance of underwater gliders
2012 Oceans, 2012Underwater gliders are efficient mobile sensor platforms that can be deployed for months at a time, traveling thousands of kilometers. As with any vehicle, different applications impose different mission requirements which impact vehicle design. In this paper, we consider a conventional glider configuration and investigate the relationship between ...

Dynamics of underwater gliders in currents
Ocean Engineering, 2014Although underwater vehicles often operate in time-varying, nonuniform currents, the effect of flow gradients on vehicle dynamics is typically ignored in motion models used for control and estimation. Forces and moments due to a nonuniform flow field are strongest when apparent mass effects are important and flight paths are most sensitive to these ...

Underwater Gliders for Ocean Research
Marine Technology Society Journal, 2004Underwater gliders are autonomous vehicles that profile vertically by controlling buoyancy and move horizontally on wings. Gliders are reviewed, from their conception by Henry Stommel as an extension of autonomous profiling floats, through their development in three models, and including their first deployments singly and in numbers.
