Control of an Unmanned Surface Vehicle With Uncertain Displacement and Drag [PDF]

IEEE Journal of Oceanic Engineering, 2017
Experimental testing of an unmanned surface vehicle (USV) has been performed to evaluate the performance of two low-level controllers when displacement and drag properties are time-varying and uncertain. The USV is a 4.3 meter long, 150 kilogram wave adaptive modular vessel (WAM-V) with an inflatable twin hull configuration and waterjet propulsion ...
