We have investigated the usefulness of active stabilizing system to reduce ship rolling under disturbances, using reaction of the flaps. In the proposed anti-rolling system for a ship, the flaps as the actuator are installed on the stern side in order to reject rolling motion induced by disturbances like wave. The action induced by the flaps depends on power of disturbances and can take the ship balance. In this study, we define the controlled system using the frequency responses obtained from the experiments. Especially, in this study we do not consider the structure of controlled system(scaled ship). The model identified from experiment and spectral analysis was used to design the controller. Hence, the usefulness of the proposed anti-rolling system was evaluated.
