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

Complexity, 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.

Receding horizon control for persistent monitoring tasks with monitoring count requirements

IET Control Theory &Applications, Volume 18, Issue 14, Page 1836-1845, September 2024.
In order to control the agent for persistent monitoring of a set of targets with the required monitoring frequency, a reachability‐based receding horizon control algorithm is proposed in the definition of Signal Temporal Logic (STL) specifications to minimize global monitoring uncertainties.

Acoustic tracking of moving marine targets using a single autonomous surface receiver

Journal of Field Robotics, Volume 41, Issue 5, Page 1498-1520, August 2024.
Abstract While marine animal behavior is often studied in constrained lab setups, a more reliable exploration should be done in their natural environment and without human interference. This task becomes excessively more challenging when quantitative data are needed in large and unconstrained aquatic environments.
