摘要
动力定位系统是通过自身的动力推进器来平衡外力作用,使船舶的航行方向及速率按照预设有序进行。其中推力分配优化是动力定位的重要组成部分,在此根据实际的船舶运行环境确定各种外力变换,进一步给出动力定位系统中推力分配优化问题的目标函数及约束条件,从而可以利用各类多目标算法进行求解。本文首先研究海上航行船舶受到的外力及运动模型,在此基础上设计基于遗传算法的船舶动态控制中的推力分配优化算法,最后进行仿真。
Dynamic positioning system is used to balance the force through its propulsion, the ship will sail accordance with default rate and direction. Thrust allocation optimization is an important part of the dynamic positioning, according to the running environment of the ship, various external forces are determined, the constraint condition of the objective function for the optimization problem of thrust allocation in power system is presented, it can be solved by all kinds of multi-objective algorithms. This paper study the external force and motion model of the ship, design the thrust allocation algorithm in ship dynamic control based on genetic algorithm, finally, the simulation is carried out.
