Data-driven model predictive control of underactuated ships with unknown dynamics in confined waterways

open access: yesJournal of navigation, 2022
Inland waterway transportation is one of the most important means to transport cargo in rivers and canals. To facilitate autonomous navigation for ships in inland waterways, this paper proposes a data-driven approach for predictions and control of ...

Are We Ready for Unmanned Surface Vehicles in Inland Waterways? The USVInland Multisensor Dataset and Benchmark [PDF]

open access: yesarXiv, 2021
Unmanned surface vehicles (USVs) have great value with their ability to execute hazardous and time-consuming missions over water surfaces. Recently, USVs for inland waterways have attracted increasing attention for their potential application in autonomous monitoring, transportation, and cleaning.

Adaptive Alignment for Low-Cost INS in ECEF Frame Under Large Initial Attitude Errors

open access: yesNavigation, 2023
A new two-stage alignment on a moving base is proposed for a low-cost inertial navigation system with the aid of a Global Positioning System (GPS) receiver in the Earth-centered, Earth-fixed (ECEF) frame under large initial attitude errors.

Euclidean Distance Matrix-Based Rapid Fault Detection and Exclusion

open access: yesNavigation, 2023
Faulty signals from global navigation satellite systems (GNSSs) often lead to erroneous position estimates. A variety of fault detection and exclusion (FDE) methods have been proposed in prior research to both detect and exclude faulty measurements. This

Nonlinear Model Predictive Control with Obstacle Avoidance Constraints for Autonomous Navigation in a Canal Environment [PDF]

open access: yesarXiv, 2023
In this paper, we describe the development process of autonomous navigation capabilities of a small cruise boat operating in a canal environment and present the results of a field experiment conducted in the Pohang Canal, South Korea. Nonlinear model predictive control (NMPC) was used for the online trajectory planning and tracking control of the ...

Fault detection and isolation in flat navigation canals

open access: yesInternational Conference on Control, Decision and Information Technologies, 2017
Inland navigation networks are composed of several artificial canals that are characterized by no slope. These canals are particularly subject to resonance phenomena, which can create waves such that the navigation condition might not be guaranteed.

Modeling of Two Sub-reach Water Systems: Application to Navigation Canals in the North of France

open access: yesInternational Conference on Informatics in Control, Automation and Robotics, 2017
Inland navigation networks are large-scale systems that can be described by using the nonlinear Saint-Venant partial differential equations. However, as there is no analytical solution for them, simplified models are used instead for modeling purposes ...
