Automatic Berthing System Using Expert System

open access: yesJournal of the Society of Naval Architects of Japan, 1993
Berthing is mode up of an approach in a restricted water area and the final berthing manoeuvre to stop. In this paper, an expert system is used to include decision making processes in berthing. The expert system essentially consists of two independent expert systems which are charge of planning and control execution respectively.

Model Reference Adaptive Control-Based Autonomous Berthing of an Unmanned Surface Vehicle under Environmental Disturbance

open access: yesMachines, 2022
Surface-vehicle berthing is a complex and challenging task. It involves complicated ship dynamics owing to a large drift angle and the time-varying environmental disturbances induced by wind, wave, and current.

An Application of ANN to Automatic Ship Berthing Using Selective Controller [PDF]

open access: yesTransNav, 2007
This paper deals with ANN(Artificial Neural Networks) and its application to automatic ship berthing. As ship motions are expressed by a multi-term non-linear model, it is very difficult to find optimal methods for automatic ship berthing.

A Bidirectional Imitation-Learning Framework for Real Time Trajectory Planning in Automatic Berthing [PDF]

open access: yesTransNav
This paper presents a bidirectional imitation-learning framework for AIS-based real-time trajectory planning in automatic berthing. The framework connects a ship’s current state with a prescribed terminal berthing condition by using two imitation ...

Automatic Ship Berthing Using Parallel Neural Controller [PDF]

open access: yesIFAC Proceedings Volumes, 2001
Abstract In this paper a parallel ANN(artificial neural networks) for the automatic berthing will be discussed. This controller has a separated hidden layer each control an engine and a rudder respectively. Using this controller simulations were carried out where the initial conditions such as ship's positions and heading angle are different from ...
