POSITION CONTROL SYSTEM OF MULTIPLE OBJECTS AND METHOD FOR SHIP

摘要

The present invention relates to a multi-body position control system and a method for controlling the position thereof, by collecting information on a target around a ship at sea to reduce the possibility of collision with the target. According to an embodiment of the present invention, a position control system for controlling the position of a ship on the sea, the ship information measuring device installed on the ship and measuring the external force information applied to the ship and the location information of the ship; A thruster for adjusting the position of the ship; A target position measuring device installed on the ship to measure the position of the target; A distance meter that measures a distance from the target by detecting a laser signal reflected back after firing a laser signal toward the target; And a thrust control signal to the thruster to maintain a predetermined position based on the external force information measured through the ship information measuring device and the position information of the corresponding ship, but the position and target of the target received from the position measuring device and the distance measuring device. Provided is a ship position control system, characterized in that it comprises a DP controller for generating a thrust control signal for collision avoidance so as not to collide with the target based on the distance to the thruster.
