Three-ring adaptive magnetic levitation active driving mass anti-sway device and control method thereof

Abstract

The invention provides a three-loop self-adaptive magnetic levitation active drive mass block anti-sway device, which adopts a three-loop control strategy based on current, speed and position, and combines with a system model to precisely control the mass block. At the same time, according to the wave frequency and the angle between the ship's driving direction and the sea wave, an adaptive control regulator is designed, combined with the system model, to predict the most reasonable position of the mass block in advance, and control the mass block to reach the optimal position, so that when the ship is affected by the external environment such as waves When the disturbance occurs, the center of gravity of the ship can be changed by controlling the position of the mass block to suppress the roll of the ship. The device of the present invention can accurately control the mass block to reach the ideal position so as to automatically realize the anti-rolling of the ship, and the ship is in a high-speed, low-speed or mooring state. It has nothing to do with the wave frequency and the angle between the direction of the ship and the wave. Therefore, the three-ring adaptive magnetic levitation active drive mass is suitable for anti-rolling in all ship fields and under all working conditions.

Description

technical field [0001] The invention relates to the field of anti-rolling devices, in particular to a three-ring self-adaptive magnetic suspension active-driven mass block anti-rolling device. Background technique [0002] Due to its indispensable role, ship roll stabilization devices have been widely studied. At present, many scholars are conducting research on new anti-rolling devices and combined anti-rolling devices. The research on joint anti-rolling leads to more complex structure and higher cost of anti-rolling devices. The traditional anti-rolling weight device changes the position of the ship's center of gravity by moving the weight, so as to achieve the goal of anti-rolling, and compared with the anti-rolling water tank, the anti-rolling weight device has all its weight can be used for anti-rolling and installation Convenience and other advantages. However, the traditional anti-rolling weight device has the disadvantages of consuming a lot of energy and slow resp...
