In view of the unmanned aerial vehicle (UAV) three-dimensional path planning problem, an enhanced multi-strategy dung beetle algorithm of UAV path planning is proposed・ Firstly, constraints on the flight proximity rate and response time are introduced and added to the threat cost, considering the influence of UAV turning performance, a three-dimensional task space model and trajectory cost function are established・ Secondly, the dung beetle algorithm is enhanced by introducing offset estimation strategy, variable spiral search strategy, quasi-inverse learning strategy, and dimensional mutation strategy to improve the algorithm's global optimization capability and convergence speed.・ Finally> simulation results of the improved algorithm for three-dimensional trajectory planning in an environment are presented・ Results demonstrate that by considering both the maneuverability and turning performance of the UAV, the planned path can safely and efficiently avoid hazards・ Compared to other algorithms, the enhanced multi-strategy dung beetle algorithm shows better optimization capability and generates higher-quality trajectories・ [ABSTRACT FROM AUTHOR] |

针对无人机(unmanned aerial vehicle, UAV)三维航迹规划问题,提出一种增强型多策略蜿螂算法的 UAV航迹规划方法。首先, 将飞行接近率和响应时间的动态约束添加到威胁成本代价中, 并考虑UAV转弯性能 的影响, 建立三维任务空间模型与航迹代价函数。其次, 在蜿螂算法中引入偏移估计策略、变螺旋搜索策略、准反 向学习策略和逐维变异策略, 提高算法的全局寻优能力和收敛速度。最后, 给出了改进算法在三维环境下航迹规 划的仿真结果。结果表明：综合考虑UAV机动性能和转弯性能, 规划出的路径可以更加安全有效地避开危险源。 相比其他算法, 改进算法的寻优能力更好, 规划的航迹质量更优。.
