Active gyroscope-based ship stabilization device

Abstract

The invention relates to a ship oscillation stabilization device using an actively controlled gyroscope, where the gyroscope is mounted on a support with three degrees of freedom corresponding to the Roll, Pitch, and Yaw axes. The device also includes a multi-axis sensor to measure the ship's oscillation state and a central controller configured to process the sensor signals, thereby simultaneously controlling the support axes to orient the gyroscope position to generate the optimal moment to cancel out the oscillation moments generated by waves acting on the ship's hull. By determining the ship's total oscillation, the device is controlled to generate actively adjusted directional response moments to simultaneously cancel out oscillations along the Roll, Pitch, and Yaw axes, and to cancel out any additional moments arising during pre-rotation.The device allows the use of a single gyroscope while maintaining high stability, contributing to reduced size, weight, and cost, as well as improved operational efficiency and expanded applicability on small vessels.
