Automatic Berthing Using the Expert System
IFAC Proceedings Volumes, 1992Abstract The automatic berthing by the expert system is presented in this paper. The system is made on the desktop simulator on the Sun-3 workstation combined with the OPS83 expert system to deal with the final approach and berthing. The rules for the berthing were obtained through the simulation by the authors. Fairly good berthing had been achieved

Local navigation system for automatic ship berthing
Infocommunications and Radio Technologies, 2018This paper shows that it is necessary to solve the problem of accurate ship positioning to provide automatic ship berthing. It is impossible to solve this problem using global positioning systems since they do not provide the proper precision. The principles and methods of development of a local navigation system are discussed.

An Automatic Berthing Study by Optimal Control Techniques
IFAC Proceedings Volumes, 1992Abstract In this paper, the optimal control problem for ship's automatic berthing is discussed. Some optimal solutions are obtained by solving nonlinear two-points boundary value problems. The equations of motions in berthing maneuvering arc represented by sophisticated nonlinear mathematical model.

A study on automatic ship berthing system design
2009 International Conference on Networking, Sensing and Control, 2009The berthing is one of the most sophisticated control action carried out by human operators, especially when the disturbance due to wind and current become relatively large with a small ship velocity. Since, to improve the flexibility and safety' ship for berthing, auxiliary maneuvering measures such as bow and stern thrusters have come to be attached.

Minimum time-energy trajectory planning for automatic ship berthing
IEEE Journal of Oceanic Engineering, 1995A ship optimal trajectory planning method based on the dynamic model of the ship is presented. First a mathematical modular model is introduced for describing the non-linear dynamics of the ship. Then the problem of optimal trajectory planning is discussed.

Optimal Energy Trajectory Planning and Control for Automatic Ship Berthing
2020 39th Chinese Control Conference (CCC), 2020This 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.

Operation of local positioning system for automatic ship berthing
2017 IEEE East-West Design & Test Symposium (EWDTS), 2017The 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
