Automatic vessel position holding control method and controller
An automatic vessel position holding control method for holding a vessel position and a vessel heading of a vessel on the ocean in order to reduce a positional deviation and a heading deviation sharply as compared with the conventional automatic vessel position holding control by performing feedforward control for estimating and then compensating for at least one of a wave drifting force and a wave drifting moment that act on the vessel, wherein a vessel position holding control is performed that includes such controls as estimating waves entering the vessel from motion thereof, calculating at least one of the wave drifting force and the wave drifting moment from the estimated waves and performing feedforward control for at least one of the calculated wave drifting force and the calculated wave drifting moment.
