PROBLEM TO BE SOLVED: To provide a ship attitude control method guaranteeing stability, and capable of controlling only a necessary frequency band. SOLUTION: This ship attitude control method uses a hull attitude controller having fin stabilizers provided on both side face parts of a hull, a sensor detecting a roll angular velocity or a roll angle of the hull, and a control calculation part outputting a proper operation amount to each the fin stabilizer based on a detection value of the sensor so that a proper roll angle is always maintained. Alternatively, the ship attitude control method uses a hull attitude controller having a trim tab provided in a rear end bottom part of the hull, sensors each detecting a pitch angular velocity/roll angular velocity or a pitch angle/roll angle of the hull, and a control calculation part outputting a proper operation amount to the trim tab based on detection values of the respective sensors so that a proper pitch angle/roll angle is always maintained. In the ship attitude control method, the output control to the fin stabilizer or the trip tab by the control calculation part is executed by an H infinity control method. COPYRIGHT: (C)2003,JPO
