Ship fin stabilizer and wing fin vector control method

Abstract

The invention provides a ship fin stabilizer and wing fin vector control method. The method includes transmitting current ship rolling information measured by a rolling sensor to an intelligent ship stabilizing regulator; performing ship stabilizing robust control algorithm calculation according to the current rolling information to obtain rolling stabilizing control torque needed by stabilizing; performing intelligent decision algorithm calculation on a fin stabilizer angle and a wing fin angle according to the needed rolling stabilizing control torque to obtain needed fin stabilizer angle and wing fin angle instruction signals; transmitting the fin stabilizer angle and wing fin angle instruction signals to a fin stabilizer and wing fin servo system through an asynchronous serial communication interface to drive and control a fin stabilizer and a wing fin so as to provide the needed rolling stabilizing torque and reduce ship rolling. By the ship fin stabilizer and wing fin vector control method, a ship stabilizing effect can be achieved, energy consumption can be lowered, and the all-weather navigability and reliability of a ship can be improved.

Description

Technical field [0001] The invention relates to a ship fin stabilizer control method, in particular to a ship fin stabilizer-wing fin vector control surface synergistic energy-saving control method. Background technique [0002] Ship fin stabilizer is an active control type anti-rolling device, which has been recognized as an effective technology for ship anti-rolling. The effect of anti-rolling is relatively ideal. It has been widely used in various ships at home and abroad. For the non-retractable fin stabilizer system, it is mainly composed of the fin and mechanical transmission device, the servo system for driving the fin, and the stabilizer controller. For two pairs of non-retractable ship anti-rolling control systems, the structural schematic diagram is as follows figure 1 Shown. [0003] Non-retractable fin stabilizers require symmetrical lift when the fins are at positive and negative rotation angles, the lift is large, the resistance is small, the fin torque is small, the...

Problems solved by technology

The anti-rolling effect of the existing ship stabilizer fins is limited

On the other hand, the drive fin servo mechanism is a high-power system with high energy consumption, so energy-saving control technology is also a problem that needs to be considered
