摘　　要：采用动力定位系统进行船舶精确定位为船舶在海上作业的正常进行提供了保障。其中如何进行推力分配是实现精确定位的主要难题,为了降低船舶动力定位的功率消耗、硬件磨损,提出一种基于改进果蝇优化算法的船舶推力分配方式。优化不同方向推进器的推力和角度,在模型满足各种约束的条件下,使船舶推进系统功率消耗最小。仿真结果表明,改进后的果蝇优化算法相较于传统果蝇优化算法能够减小船舶的功率消耗,让船舶的推进角、推力更加顺滑,从而降低船舶硬件的磨损。The use of power positioning system for precise positioning of ships provides a guarantee for the normal operation of ships at sea.In order to reduce the power consumption and hardware wear of ship power positioning,a ship thrust distribution method based on improved fruit fly optimization algorithm is proposed.The thrust and angle of thrusters in different directions are optimized so that the model satisfies various constraints to minimize the power consumption of the ship propulsion system.The simulation results show that the improved Drosophila optimization algorithm can reduce the power consumption of the ship compared with the traditional Drosophila optimization algorithm,make the propulsion angle and thrust of the ship smoother,and thus reduce the wear and tear of the ship hardware.
