The mode of the anti-roll moment generated by the anti-roll gyro is positively correlated with the mode of the momentum moment and the precession angular velocity of the gyro rotor and negatively correlated with the precession angle. Under the condition that the moment of inertia and the rotating speed of the gyro rotor are fixed, the precession angle and the angular speed of the gyro are controlled by applying the precession moment, and the gyro anti-rolling moment is further controlled, so that the purpose of reducing the disturbance of platforms such as ships is achieved.
