IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This paper proposes a composite control strategy combining a disturbance observer (DOB) and an adaptive sliding‐mode controller (ASMC) to enhance the path‐tracking performance of underactuated unmanned surface vehicles. The DOB actively compensates for environmental disturbances while the ASMC handles model uncertainties, with simulations demonstrating

Numerical Simulation of the Motion of a Large Scale Unmanned Surface Vessel in High Sea State Waves
Journal of Marine Science and Engineering, 2021 The motion stability of the Unmanned Surface Vessel (USV) is threatened by the action of waves under a rough sea state. In the present paper, the motion of a large-scale USV is numerically simulated under high sea state of level 5 and 7. The overset grid

Journal of Field Robotics, Volume 42, Issue 8, Page 4215-4235, December 2025.ABSTRACT In this study, we tackle the problem of surveilling a large area over the sea without access to the global navigation satellite system (GNSS) while searching for the known target vessel. The system utilizes an unmanned aerial vehicle (UAV) equipped with long‐range radio frequency (LoRa) localization and an RGB camera to detect the target ...
