摘　　要：零航速减摇鳍常规减摇和零航速减摇两种模式下生力机理不同而导致控制策略不尽相同。本文从两种模式下生力机理出发,分析海浪干扰、船舶横摇、鳍的动作及鳍上产生的减摇力之间的相位关系,分别得出两种模式下反馈控制策略。通过与常规减摇鳍控制方法对比,不仅验证了所得常规减摇模式下的控制策略的正确性,而且也验证了相位匹配分析方法的适用性;而零航速减摇模式下的控制策略则通过仿真和水池试验进行验证。结果表明:基于相位匹配得到的零航速减摇鳍的控制策略是有效且实用的,可为实际工程应用提供参考。The zero-speed fin stabilizer has different force generation mechanisms in normal anti-rolling mode(NAM)and Zero-speed anti-rolling mode(ZSAM),such difference causes different control strategies.In this paper,the feedback control strategies for the two modes were obtained by analyzing the phase relationships among wave disturbance,rolling of ship,fin movement and the anti-rolling force generated on the fin on basis of the force generation mechanisms of the two working modes.By comparing with the control method of the conventional fin stabilizer,both the correctness of the control strategies in the normal anti-rolling mode and the applicability of the phase matching analysis method were verified;while the effectiveness of the control strategies obtained in the zero-speed anti-rolling mode was demonstrated through simulations and water tank test.The results show that the control strategies obtained on basis of phase matching are effective and practical,they can provide a reference for actual engineering application.
