METHOD OF CONTROLLING SHIP TRAJECTORY Russian patent published in 2013 - IPC G05D1/00 

FIELD: physics.

SUBSTANCE: method of controlling ship trajectory employs current values of magnitudes and directions of linear velocity vectors $${\overline{\upsilon }}_F$$ of the head F point and $${\overline{\upsilon }}_A$$ stern A point. Vector directions are controlled based on the condition of their constant direction at a given point in a fixed coordinate system X₀0Y₀, specifically the vector $${\overline{\upsilon }}_F$$ during movement is directed towards the final given position of the head point of the ship F_K, and the vector $${\overline{\upsilon }}_A$$ during movement is directed towards the final given position of the stern point of the ship A_K; magnitudes are controlled by estimating the ratios of the given values of each of the magnitudes to the corresponding current values of said magnitudes; a control signal σ is generated from values of differences between current and given values of magnitudes and vector directions $${\overline{\upsilon }}_F$$ and $${\overline{\upsilon }}_A.$$

EFFECT: high efficiency of using ship control equipment.
