摘　　要：针对SWATH船实航时产生的水平筛动问题,研究由横荡、横摇和艏摇的耦合运动产生的船舶运动中断(MII),提出设计SWATH船稳定鳍减横摇控制器,减小MII。通过理论分析MII产生原因和SWATH船稳定鳍工作时产生减摇作用的力和力矩特性,验证利用稳定鳍减小SWATH船横摇运动,抑制MII的可行性。在保证SWATH船升沉和纵摇运动的基础上,设计稳定鳍减横摇控制器,减小SWATH船横摇。仿真结果表明,控制器使SWATH具有良好的纵向运动性能,有效减小了横摇运动,抑制MII。Vibration problem may occur when a SWATH ship sails in a sea way. The MII induced by sway, heave and yaw motions is discussed And roll controller of SWATH stabilizer fins is proposed The reason of MII is discussed And forces and moments worked by fins are analyzed to show the feasibility of roll reduction and 3411. On the base of controller of stabilizer fins for SWATH heave and pitch motions, the roll reduction controller is designed Simulation results show that the controller can get good performance of SWATH ship motions. It can also get good reduction of roll motions and reduce MII of SWATH ship.
