Adaptive Sliding Mode Path Tracking Control for an Underactuated Unmanned Surface Vehicle Based on a Disturbance Observer

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

Fixed‐Time Fault‐Tolerant Formation Control for Uncertain Nonlinear Multi‐USVs With Actuator Failures

Complexity, Volume 2026, Issue 1, 2026.
The fixed‐time fault‐tolerant formation control (FTFC) issue is investigated for nonlinear multi‐USVs considering unknown dynamics, external disturbances, and time‐varying actuator failures. To further mitigate the burden on the channel, a nonmonitoring adaptive periodic event‐triggered quantized (NM‐APETQ) mechanism is devised, in which the quantized ...

Aerial Localization and Navigation for Surveillance of Large, Featureless, GNSS‐Denied Maritime Environments

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 ...
