Path Following Problem for a DP Ship Simulation Model
1 Maritime University of Szczecin, Szczecin, Poland
ABSTRACT: For the dynamic positioning (DP) operations the equations of ship's motion can be simplified to a 3 degrees-of-freedom (DOF) model. DP station-keeping is a set-point regulation problem, i.e., forcing the output of the ship to maintain a constant reference position and heading. However since offshore vessels reposition themselves at different locations, the path following problem has to be solved. The article presents various solutions of this problem including fuzzy control design which could be utilised in autonomous ship simulation as well.
