Title:
ACTIVE HEAVE COMPENSATION-BASED ANTI-SWING METHOD FOR SHIP
Document Type and Number:
WIPO Patent Application WO/2024/026985
Kind Code:
A1
Abstract:
An active heave compensation-based anti-swing method for a ship, comprising the following steps: using an automatic anti-swing control algorithm of an energy dissipation-based underactuated system to analyze energy dissipation, and allocating energy according to the actual working condition of the system; in combination with a time series-based wave motion short-term forecasting algorithm, using a displacement sensor and a hydraulic compensation cylinder system to analyze wave motion, segmenting the trajectory of the wave motion according to the time, and under a set fixed step size, a controller predicting and analyzing the actual trajectory of the system under a next step size; on the basis of an extended Kalman filtering-based signal acquisition method, and by using a linear system state equation, observing and collecting data by means of input and output of the system; and controlling a heave compensation system by means of a core intelligent control algorithm for heave compensation under time lag. According to the active heave compensation anti-swing method for a ship, by means of intelligent control, the responsiveness of the system can be improved, and delay faults of the system can be reduced.
