GL‐LoiterDNet: A Hybrid Model for Ship Trajectory Prediction in Loitering Activity Scenarios
Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.In loitering activity scenarios, vessels frequently execute course changes within localized maritime spaces, often exhibiting extreme turning maneuvers that generate ultralong, dense, and highly nonlinear spatiotemporal trajectories. Traditional prediction models demonstrate limitations in processing dynamically changing trajectory features, leading to

Study on path planning of unmanned surface vessel based on data-driven genetic algorithm
智能科学与技术学报, 2019 The genetic algorithm (GA) is an effective method for the path planning system of unmanned surface vessel (USV),but it is easy to fall into local optimal precocity and converges slowly.For this,without increasing the complexity of the algorithm,a data ...

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.
