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
