SYSTEM AND METHOD FOR TESTING DYNAMIC POSITIONING CONTROLLER SYSTEM OF A MARINE VESSEL

摘要

The present invention is a verification system for verifying a dynamic positioning control system generating a control signal including final destination information of a ship based on a simulated sensor signal. The verification system comprises: an actuator simulator for receiving input of a control signal including final destination information of a ship and continuously generating a modeled control signal including thrust information; an actuator modulator for receiving the modeled control signal including thrust information and generating a distorted modeled control signal including thrust information via calculation processes according to a test condition; a ship simulator for receiving the distortion based modeled control signal and performing ship movement analysis; and a sensor simulator for measuring a simulated sensor signal from the ship simulator, wherein the actuator modulator modulates the modeled control signal of the actuator simulator to enact an abnormal operation of the actuator simulator, thereby verifying impact of distorted modeled control signal on the dynamic positioning control system.
