舰船减摇的趋近律滑模控制

Approximate law sliding mode control of ship

船舶减摇鳍的存在,在一定程度上提升了船舶航行的稳定性,同时也大大改善了航行控制的效果,尤其是在船舶作高速的航行和转向动作时,由于减摇鳍的作用,船体能够最大限度保持稳定。但在减摇鳍的控制过程中,其工作模式一般处于非线性状态,因此,控制电机的反馈作用对减摇效果会产生直接影响。本文重点探究减摇控制电机的工作状态,采用二阶趋近滑动控制算法对电机的控制流程进行优化,在遇到突发情况时,能够主动增强反馈效果,提升稳定器的作用时间,从而保证减摇效果。

The existence of ship fin stabilizer enhances the stability of ship navigation to a certain extent, and also greatly improves the effect of navigation control. Especially when the ship is engaged in high speed sailing and steering action, due to the effect of fin stabilizer, the hull can be kept to a maximum. However, in the control of the fin stabilizer, its working mode is generally in a non-linear state, so the feedback effect of the control motor will have a direct effect on the anti-roll effect. The main work of this paper is to focus on the working state of the motor, and the second-order approach sliding control algorithm is used to optimize the control flow of the motor. In the event of sudden situation, the feedback effect and the stabilizer's role of time can be enhanced, thus ensuring the effect of reducing the shake.
