Abstract |
In this paper, Artificial Neural Network(ANN) ís applied to automatic berthing control for a ship. ANN is suitable for a maneuvering such as ship's berthing, because it can describe non-linearity of the system Multi-layer perceptron which has more than one hidden layer between input layer and output layer is applied to ANN Using a back-propagation algorithm with teaching data, we trained ANN to get a mínímal error between output value and desired one. For the automatic berthing control of a containership, we introduced low speed maneuvering mathematical models. The berthing control with the structure of 8 input layer units in ANN is compared to 6 input layer units. From the simulation results, the berthing conditions are satisfied, even though the berthing paths are different. |
