Physics‐Informed Hybrid Framework for Integrated Ship Motion and Carbon Emission Prediction

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper presents a gray‐box physics‐informed neural network (PINN) that integrates maneuvering modeling group (MMG) ship dynamics with a residual attention learner trained on data. By combining physics‐constrained loss with data‐driven residual modeling, the framework achieves accurate and robust prediction of ship motion and fuel consumption, with ...

Energy efficiency of ship propulsive systems: rudder-propeller interaction

, 2010
The rudder of a ship is used to maintain its direction and for changing course. As such the goal of rudder design is to maximise sideforce for control of course while minimising resistive drag.

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

Effects of Rudder Position on the Ship Maneuvering

, 2017
The performance of the rudder on a ship affects the ability of the vessel to maneuver effectively. In the current study evaluation is made on the rudder mounted on a twin screw fast boat with LOA of 59.2 m and Vs of 28 knots.

Robust Yaw Angle Control of an AUV: Terminal Sliding Manifold Based Optimized Super‐Twisting Algorithm

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a robust adaptive control scheme for an autonomous underwater vehicle to achieve precise path tracking under model uncertainties and ocean disturbances. The design integrates a non‐singular terminal sliding mode, an adaptive super‐twisting algorithm optimized via improved Aquila optimization, and an uncertainty disturbance estimator

Analysis of the Cavitating Flow Around the Horn-type Rudder in the Race of a Propeller

, 2001
This paper describes numerical methods by a mixed formulation of the boundary value problem (BVP) for the prediction of the cavitating flow around the horn-type rudder working behind a propeller.

Research on Design and Energy-Saving Performance of Gate Rudder

Journal of Marine Science and Engineering
As a novel energy-saving and maneuvering device for ships, the gate rudder system (GRS) functions similarly to an accelerating duct. While providing additional thrust, its independently controllable rudder blades on either side of the propeller also ...
