Lagrangian Modelling of an Underwater Wave Glider
Ship Technology Research, 2012AbstractThis paper introduces a control-oriented modelling approach for a hybrid autonomous underwater vehicle, the Underwater Wave Glider. The vehicle can accomplish both surface and underwater tasks by changing its shape: it can operate as a wave glider at the sea surface, exploiting wave and solar energy to recharge the onboard batteries, and switch

Dynamic modeling of a wave glider
Frontiers of Information Technology & Electronic Engineering, 2017We propose a method to establish a dynamic model for a wave glider, a wave-propelled sea surface vehicle that can make use of wave energy to obtain thrust. The vehicle, composed of a surface float and a submerged glider in sea water, is regarded as a two-particle system. Kane’s equations are used to establish the dynamic model. To verify the model, the

Autonomous front tracking by a Wave Glider
OCEANS 2016 MTS/IEEE Monterey, 2016Coastal upwelling brings cooler, saltier, and nutrient-rich deep water upward to the surface. Upwelling fronts support enriched phytoplankton and zooplankton populations, thus having great influences on ocean ecosystems. We have developed a method to enable a Wave Glider (an autonomous surface vehicle) to autonomously detect and track an upwelling ...

Monitoring marine mammal acoustics using Wave Glider
OCEANS 2010 MTS/IEEE SEATTLE, 2010The Wave Glider, a wave-powered unmanned maritime vehicle (UMV), represents a novel and unique approach to persistent ocean presence. Wave Gliders harvest the abundant energy contained in ocean waves to provide essentially limitless propulsion. The Wave Glider can operate as a vessel, covering long distances in the ocean, or as a station-keeping ...

Lagrangian modeling of the Underwater Wave Glider
OCEANS 2011 IEEE - Spain, 2011This paper introduces a control-oriented modeling approach for a hybrid autonomous underwater vehicle: the Underwater Wave Glider. Thanks to a non-conventional design, the vehicle can accomplish both surface and underwater tasks, by changing its shape. The vehicle can operate as a wave glider at the sea surface, where the potential energy of the waves ...

Hydrodynamic Analysis of Submarine of the Wave Glider
Advanced Materials Research, 2013Wave glider harvests the abundant ocean wave energy for long term ocean cruising due to its particular two-part architecture. Its submerged part named glider converts vertical fluctuation of waves to horizontally forward propulsion. Because of the uncertainty of the ocean condition and irregularity of its wave motion, the design parameters of the ...
