Path‐following algorithms and experiments for an unmanned surface vehicle [PDF]
Journal of Field Robotics, 2009 AbstractThis paper addresses the problem of path following in two‐dimensional space for underactuated unmanned surface vehicles (USVs), defining a set of guidance laws at the kinematic level. The proposed nonlinear Lyapunov‐based control law yields convergence of the path‐following error coordinates to zero.

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 ...
