Operation of local positioning system for automatic ship berthing

open access: closed2017 IEEE East-West Design & Test Symposium (EWDTS), 2017
The article deals with principles and methods of development of local navigation system based on the homodyne signal transforming. Such approach let us distance determination with the help of simplest system design. The block diagrams of system elements are given and the principles of its functioning are described. The use of the proposed block diagram

A multivariable neural controller for automatic ship berthing

open access: closedIEEE Control Systems, 1997
This article describes the development and application of a multivariable neural controller for automatic ship berthing. Following a brief review of various methods employed in automatic ship control, an online trained, backpropagation-based neural network controller is presented.

Ship Automatic Berthing Control with State Constraints Using Speed Assignment

open access: closed2025 37th Chinese Control and Decision Conference (CCDC)
Considering the nonlinearity of the ship kinematic and dynamics model, the accuracy required for automatic berthing, and the speed control during berthing, this paper proposes an automatic berthing method with state constraint control algorithm and speed

Optimal Energy Trajectory Planning and Control for Automatic Ship Berthing

2020 39th Chinese Control Conference (CCC), 2020
This paper proposes an optimization method for the ship's optimal berth trajectory based on the ship dynamics. By introducing a mathematical dynamic model which helps to describe the nonlinear dynamic system of a ship, this paper attempts to solve the problem of optimal trajectory planning for ship berthing.

Artificial Neural Network controller for automatic ship berthing: challenges and opportunities

Marine Systems & Ocean Technology, 2020
Ship berthing is a complicated manoeuvring process that demands precise control of the speed and course of an under-actuated system. As berthing involves low speed running of a ship under environmental disturbances with reduced manoeuvrability, a professional ship handler often faces difficulties in controlling heading in such a situation.
