METHOD FOR CONTROL OF VESSEL MOTION ON ARISEN SEA Russian patent published in 2009 - IPC B63H25/04 

FIELD: transportation.

SUBSTANCE: in method they use signals of course angle and angular speed from detectors of course angle and angular speed, and also from setter of course angle, which are summed in summator and supplied to input of steering gear. In process of voyage, via time interval "T", in unit of relay actuation time interval limits, signal is generated, which is supplied to inlet of relay for disconnection of course angle detector signals, setter of course angle and angular speed detector from summator and connection of helm angle average value signal from unit of helm angle average value to summator inlet. Via the following interval of time "Δt", signal generated in unit of relay actuation interval limits setting, is disconnected from relay. Signals of course angle detector, setter of course angle and detector of angular speed, previously disconnected from summator, are again connected, and previously connected signal of helm angle average value is disconnected from inlet of summator. Further via intervals of time "T" and "Δt", above described operations are repeated cyclically.

EFFECT: invention makes it possible to reduce load of steer drive at arisen sea without reduction of stabilisation quality, to increase safety of automatic control of vessel motion.
