Automatic berthing systems: a review on artificial intelligence methods for marine ship [PDF]

E3S Web of Conferences
One of the most challenging issues in the world of ship control is automatic ship berthing. In order for the berthing to be completed automatically and safely, the control systems must account for the ship’s dynamics at low speeds.
