摘　　要：以某30000 t举力浮船坞为研究对象,为更好地掌握其横摇运动的特性,分析浮态变化规律。根据浮船坞自身的特点,利用鲁棒控制原理,对其横摇减摇系统进行设计。并且基于灵敏度极小化的思想,对浮船坞横摇减摇控制系统进行仿真。通过分析得到,减摇控制系统对海浪干扰的抑制能力能够达到设定的干扰抑制要求。A 30000 t lifting floating dock is taken as the research object in order to better grasp the characteristics of its roll motion and analyze the floating state change law.According to the characteristics of floating dock itself,the roll damping system of floating dock is designed by the robust control principle.Based on the idea of sensitivity minimization,the roll damping control system of floating dock is simulated.Through the analysis,it is found that the ability of damping control system to suppress the wave interference can meet the set interference suppression requirements.
