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

open access: yesTransNav, 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.
