An autopilot and an anti-motion device have been developed for course keeping and reduction of roll motion. A pair of active stabilizing fins has high performance for roll angle reduction of a ship advancing in a seaway, however, due to its high cost, it seems to be not widely applied to conventional merchant ships yet. From the viewpoint of comfortable boarding, studies of roll motion reduction have been trying very often lately. While the effect of roll motion rejection by the active stabilizing fins is well known, the interference into ship responses by the rudder and the fins is not almost considered formerly in operation of the active stabilizing fins, we cannot to say that its performance is demonstrated enough. The experimental study about ship motions and its control with the rudder and the active stabilizing fins is only a few in Japan. The purposes of this study are as follows: 1) Construction of the mathematical model for ship monoeuvring motion in consideration of roll motion. 2) Construction of systems for measurement and control of the ship motion using MATLAB/Simulink language. 3) Experiment of the course keeping and reduction of roll motion with the optimal regulator and with the control system by decoupling control theory. A series of the study from mathematical model construction to tank test with the UMITAKA-MARU model has been carried out from the viewpoint of practical application, we show the results.
