Abstract

The study investigated the dynamic motion simulation of a sail-assisted ship under service conditions with respect to different wind conditions. Energy-saving effect based on the automatic control was also assessed. The line-of-sight method is used to decide the desired heading angle and then the PD (Proportional-Derivative) controller is applied to manipulate the rudder to maintain the target course. Furthermore, the way of deciding the ideal sail turning-angle based on the aerodynamic characteristic curve is established to get the maximum wind thrust on the ship. The time domain trajectory of the ship motion is simulated by the 4th order Runge-Kutta method. The mathematical model established here is useful for the prelim- naiy design of the automatic control system of sails on a ship and also helpful to the future application of wind energy on ships.
