This study investigated the performance of an antirolling system based on the Magnus effect at zero speed. The test scheme and control method were designed based on a proportional integration differentiation controller. A scaled ship model equipped with an attitude monitoring and control implementation feedback system was developed. The effects of different swing speeds and angles, cylinder surface shapes, number of effective cylinders, and target ship model rolling angles on the performance of the antirolling system were studied using a shipborne gravity slider and normal transverse regular wave. The Magnus antirolling system exhibited a better swing speed range compared to conventional methods, and its performance improved as the swing angle increased. During the zero-speed antirolling test, the velocity loop control provided a better antiroll damping effect on the ship model than the position loop control, and the bionic cylinder improved the performance more than a smooth cylinder. Moreover, the system retained good antirolling capabilities even in partial failure cases (i.e., operating with fewer cylinders). This study can contribute to the research of ship seakeeping strategies.
