A boat’s coxswain is adept at analyzing the wave environment, adjusting the craft’s propulsion system and control surfaces to mitigate its motions and reduce the chance of capsizing. There is a significant predictive component in the coxswain’s control decisions. Unmanned surface vehicles (USVs) lack the benefit of a highly trained coxswain reading and predicting oncoming waves - existing autonomous control systems are not aware of the wavefield, nor are they capable of combining near and far wave field information with current information about the craft in order to make adjustments to the propulsion system and control surfaces. This makes the USV susceptible to excessive shocks and motions, which may degrade mission performance, or capsizing. The proposed effort will develop a motion mitigation system including wave sensing and characterization, USV motion prediction, and vessel control for USVs. The system builds upon successful past and current research and development in using wave sensing data, advanced hydrodynamics for wave field reconstruction and vessel dynamics, and vessel control systems in improving steering and motion control of USVs in high sea states.
