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

TransNav, 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.

Artificial Neural Network Controller for Automatic Ship Berthing Using Separate Route

Journal of Web Engineering, 2020
The operation of ships in the port area requires not only the assistance of in-vessel equipment such as main engines and rudder, but also the assistance of external equipment such as tugboats. The complexity in the operation of ships in the port, requires control algorithm with multiple input and output for the automatic berthing control of the ship ...

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 ...

Experiment Results for Automatic Ship Berthing using Artificial Neural Network Based Controller

IFAC Proceedings Volumes, 2014
Abstract Experiment results are often worthy and would be a great topic of discussion. Since many years, research on automatic ship berthing had already been going on to make it actually possible so that one can minimize the annual cost of dock damage as well to ensure safe operation for such sophisticated multi input-multi output phenomenon.

Event-Sampled Adaptive Neural Automatic Berthing Control for Underactuated Ships Under FDI Attacks

Journal of Marine Science and Engineering
This work addresses the automatic berthing control problem of underactuated ships under false data injection (FDI) attack, and an event-sampled automatic berthing control scheme is proposed. To avoid the FDI attack signals from entering the closed-loop system through the sensor–controller channel and worsening the berthing control performance as much ...
