摘　　要：横摇是对船舶航行影响最大的运动,为减少船舶横摇人们发明了各种减摇手段,减摇鳍是其中最有效的一种。为提升减摇鳍的减摇效果,探索更优化的减摇鳍控制方法,文章主要研究减摇鳍的鳍角反馈与升力反馈之间的区别。研究结果表明:采用升力反馈可以避免采用鳍角反馈控制减摇鳍时在鳍角与升力计算中所产生的映射误差,避开了鳍角与升力间转换的不确定性,提高了减摇效果。Rolling is one of the largest sports influence on navigation of ships,in order to reduce ship rolling,various anti-rolling methods have been invented,and anti-rolling fin is one of the most effective methods among them.For the purpose of promoting the stabilization effect and exploring the optimal control strategy of anti-rolling fin,the difference between fin-angle feedback and fin-lift feedback is studied.Research results show that utilizing fin-lift feedback can avoid the mapping error in the calculation of fin-angle and lift force,which used to happen when utilizing fin-angle control.And utilizing fin-angle feedback control avoids the uncertainty from fin-angle to lift force and improves the stabilization effect.
