Abstract

It has been expected not only for crew but also for passengers to realize a ship whose rolling and other motions are small as much as possible. Restricting our consideration to the roll reduction, the conventional roll stabilization system, fins or anti-rolling tanks have been utilized as the actuator. The authors have already presented a basic control system method to rudder roll stabilization control system in the full scale experiments. In this paper, the authors present rudder roll stabilization control system. This control system is based on multivariate auto-regressive model which has been fitted by the MAICE procedure to actual the time series data of the actual rudder, yaw and roll motions recorded on board. Further the authors will statistically analyze the influence of rudder-roll-yaw coupling motion in the case of application of this advanced control method to various kinds of ship.
