Underwater glider motion control
2008 47th IEEE Conference on Decision and Control, 2008This paper describes an underwater glider motion control system intended to enhance locomotive efficiency by reducing the energy expended by vehicle guidance. In previous work, the authors derived an approximate analytical expression for steady turning motion by applying regular perturbation theory to a realistic vehicle model.

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

Steering control for underwater gliders
Frontiers of Information Technology & Electronic Engineering, 2017Steering control for an autonomous underwater glider (AUG) is very challenging due to its changing dynamic characteristics such as payload and shape. A good choice to solve this problem is online system identification via in-field trials to capture current dynamic characteristics for control law reconfiguration. Hence, an online polynomial estimator is

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

Underwater gliders are buoyancy-driven devices; they alternately reduce and expand displaced volume to dive and climb through the ocean. Gliders carry wings and control their pitch attitude to effectuate a horizontal speed component through the ocean. They turn by rolling their wings or by use of a rudder.

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.
