摘　　要：为了实现大型工程船舶的准确定位和移动,结合船舶锚泊系统模型,提出了以实现所有锚链张力值方差最小为目标函数的最优控制策略,制定了移位系统控制方案,并根据水平面至导缆孔部分锚链和水下锚链受力的不同,采用系数法将整条悬链线等效为两成分锚泊线,对传统悬链线方程作出改进。具体算例和分析表明:改进的悬链线方程更符合实际工程情况,采用该最优控制策略设计的移位方案简单可行,实现了锚链张力的合理分布和船舶的准确移位。A mobile mooring method is developed and the optimal control strategy which minimizes cable tension variance is designed to realize accurate movement of ship, based on the model of ship mooring system. According to the differences of cable forces between the part from water surface to cable hole and the part underwater, coefficient method is adopted to make whole catenary equivalent to a two-component mooring line,improvements to traditional catenary equations are made. Example calculations and analysis show that the improved catenary equations coincides with actual situation of engineering better. The schemes designed by the optimal control strategy is simple and workable, and a reasonable distribution of cable tension and accurate movement of ship is achievable.
