Abstract
We have investigated the usefulness cf active stabilizing system to reduce ship rolling under disturbances, using varying reaction cf the flaps. In the proposed anti-rolling system for a ship, the flaps as the actuator are installed on the stem to reject rolling motion induced by disturbances like wave. The action induced by flaps which depends on power of disturbances am take the ship balance. Especially, in this study we identify the controlled system under the undefined system structure using spectral analysis and experimental studies. Based on these informations, we design the controller to evaluate the usefulness of the proposed system.
선박 횡동요는 물적 손실을 초래할 뿐만 아니라, 승선자의 거주성, 안전성 및 작업능률을 저하시키는 가장 큰 요인이 된다. 횡동요억제를 위한 많은 연구는 다양한 형태의 장치개발이라는 결과를 가져왔으며 상당한 효과를 얻고 있다. 지금까지 개발 된 대부분의 장치는 그 성능을 고려하지 야더라도 특수한 목적의 선박을 대상으로 설치
