Warm-started semionline trajectory planner for ship’s automatic docking (berthing)

Ocean Engineering, 2022
In the usual framework of control, a reference trajectory is needed as the set point for a feedback controller. This reference trajectory can be generated by solving a trajectory optimization problem. This problem is a continuous optimal control problem (OCP) that is transcribed into a finite-dimensional nonlinear optimization problem (NLP) and solved ...

Automatic Ship Berthing Using Parallel Neural Controller [PDF]

IFAC 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 ...

Research on optimization of ship’s automatic berthing and unberthing control model

Journal of Physics: Conference Series, 2021
Abstract The automatic berthing and unberthing of ships is one of the very important links in the process of ship navigation. Due to the relative increase of interference from external factors such as wind, waves, currents, and the relative increase in system information, the automatic berthing and unberthing operations are more ...
