  • Patent number: 11947364
    Abstract: In a conventional vessel anti-rolling apparatus, because a large memory capacity and a high-speed high-function computing processing unit are required, the cost of the vessel anti-rolling apparatus is caused to rise. A vessel anti-rolling control apparatus and an anti-rolling control method according to the present disclosure includes an azimuth controller that outputs a first steering-angle command value for making the vessel turn to an azimuth to which the vessel should travel, based on an azimuth command signal and a yaw-angle signal, an anti-rolling controller that outputs a second steering-angle command value for reducing rolling of the vessel, based on a rolling-angle signal, a rolling-angular-velocity signal, and a vessel-speed signal, and a steering-angle controller that controls a steering angle, based on the first steering-angle command value and the second steering-angle command value.
