碩士 / 國立成功大學 / 系統及船舶機電工程學系 / 102 / In this study, simulation of a sail-assisted vessel’s ship dynamic responses under service conditions is investigated. Energy-saving effect based on automatic control was also assessed. The line-of-sight method is used to decide the desired heading angle and then a PD controller is used to manipulate rudder angle in order to maintain the target course. Furthermore, the way of deciding the ideal sail turning angle based on the aerodynamic characteristics curve is established to get the maximum thrust or minimum resistance. Ship motions were computed by the fourth Runge-Kutta method. The relative velocity has a significant effect on the thrust. Mathematical model established in this study is useful for the preliminary design of the automatic control system of sails on a ship and it’s also helpful to the future development of wind energy.
