摘　　要：采用解析的方法对减摇鳍在非定常流中的受力情况进行分析,得到了鳍上各种流体作用力的表达式。利用该升力模型对零航速减摇鳍角速度与升力的相位关系进行定量分析,提出了对二者相位差进行补偿的方法。为了解决浪级较大时无法进行相位补偿的问题,设计了根据起动和制动阶段的不同要求实时改变最大允许角速度的升力限位环节。仿真结果表明,加入升力限位环节可以有效抑制制动阶段反向升力对系统产生的不利影响。The forces on fin stabilizer in non-steady flow were analyzed analytically.Then the expression of lift produced by liquid was given.Phase difference between angular velocity and lift of fin stabilizer at zero speed was analyzed quantificational based on lift model,and the method to compensate the phase difference was presented.A lift restrictor was designed to change the angular velocity limitation to meet the different requirements for start and break,because the phase difference cannot be compensated when...
