Vessel azimuth control apparatus and azimuth control method

The objective is to obtain an azimuth control apparatus and an azimuth control method that require no excessive memory capacity and calculation time for information processing and can cope with a disturbance by adaptively adjusting a control gain while calculating changing vessel parameters online. The vessel azimuth control apparatus has an azimuth control unit that outputs a steering-angle command signal for making a vessel turn to an azimuth to which the vessel should travel, based on an azimuth command signal generated by an azimuth command generation unit, a yaw-angle signal, and a yaw-angular-velocity signal, a steering-angle control unit that controls a rudder based on the steering-angle command signal, and a control gain adjustment unit that calculates respective frequency responses of the yaw-angle signal and the yaw-angular-velocity signal to a steering-angle signal outputted by a steering-angle detection unit and then adjusts a control gain of the azimuth control unit.
