摘　　要：为了改善无人救生船在夜间航行的安全性问题,缩短救援所需的时间,需要提高无人船在夜间航行的适应力并对其航迹进行优化.本文提出一种考虑多种结构相互配合的新型结构无人船,同时将改进粒子群优化算法运用于航迹优化,对算法的重要参数以及易陷于局部最优的不足进行改进.仿真结果表明,与传统无人救生船搜救模型相比,本文提出的新型无人救生船结构与航迹优化方法能切实保障夜间救援的安全并减少航行时间.In order to improve the safety of unmanned lifeboat at night and shorten the time required for rescue,it is necessary to improve the adaptability of unmanned lifeboat at night and optimize its track.In view of the problems existing in the current night rescue,a new structure unmanned ship considering the cooperation of multiple structures is proposed.At the same time,the improved particle swarm optimization algorithm is applied to track optimization to improve the important parameters of the algorithm and the shortcomings that are easy to fall into local optimization.The simulation results show that compared with the traditional unmanned lifeboat,the new unmanned lifeboat can ensure the safety of night rescue and reduce the navigation time.
