Autonomous Underwater Vehicle Propulsion Design
… propulsive system for the candidate autonomous underwater vehicle (AUV) as possible. A mathematical approach, using fundamental motor equations and derived quantities, was used to characterize and select an efficient brushless electric motor for the propulsion system. A program developed at MIT, …

Controller design for underwater vehicle systems with communication constraints
Real-time cooperation between autonomous vehicles can enable time-critical missions such as tracking and pursuit of a dynamic target or environmental feature, but relies on wireless communications. Underwater communication is almost exclusively accomplished through acoustics, which bring challenges …
