Optimization Strategies for Auto‐Berthing of Unmanned Surface Vessels Using Differential Homeomorphism and the Gauss Pseudospectral Method

open access: yesComplexity, Volume 2025, Issue 1, 2025.
This paper designs an optimal control strategy for the auto‐berthing control (ABC) problem of underactuated surface vessels. The purpose is to achieve accurate berthing of USVs in complex environments. In the traditional ABC problem of surface vessels, the underactuated characteristics of USVs complicate the control design.
