Abstract
The concept of autonomous wind-powered vessels equipped with hydrokinetic turbines beneath the hull offers a unique offshore energy opportunity for the Navy. Such a vessel would have the ability to generate and store energy onboard, before delivering it to a nearby naval base or naval vessel. If these wind-powered vessels operated in a fleet, a control strategy would be needed to govern their motion. Unlike existing strategies used to control other types of unmanned vessels, a strategy for the wind-powered vessels would need to consider additional constraints such as wind direction and velocity. In this thesis, a four degree-of-freedom wind-powered vessel model is considered. Then a control strategy for a fleet of such vessels operating in the vicinity of a naval base is presented. Finally, some insight into the required operating area, number of vessels needed, and total energy production is given.
