Nonlinear Time-Domain Strip Theory Formulation for Low-Speed Manoeuvering and Station-Keeping [PDF]
Modeling, Identification and Control, 2004 This paper presents a computer effective nonlinear time-domain strip theory formulation for dynamic positioning (DP) and low-speed manoeuvring. Strip theory or 2D potential theory, where the ship is divided in 20 to 30 cross sections, can be used to ...
