摘要:

为解决对地形预处理后缺少与UAV自身特性相结合的问题,提出了一种基于安全飞行空间的UAV低空突防改进模型。构建了一个可安全飞行空间,减少地形约束条件的同时保证无人机低空突防时的安全飞行。结合无人机自身特性对航迹规划模型进行了改进,增加无人机飞行过程稳定性和规划的航迹平滑性。通过PSO算法在复杂的高程地图中对改进前、后2种模型进行了仿真,验证了改进后模型的合理性和有效性。

Abstract:

An improved unmanned aerial vehicle (UAV) low altitude penetration model based on safe flight space is presented to solve the problem of lack of combination with the characteristics of UAV after terrain preprocessing. A safe flight space is constructed to reduce terrain constraints and ensure the safe flight of UAV in low altitude penetration. The trajectory planning model is improved by combining with the characteristics of UAV to increase the stability of UAV flight process and the smoothness of planned trajectory. The particle swarm optimization (PSO) algorithm is used to simulate the two models before and after the improvement in complex elevation map to verify the rationality and effectiveness of the improved model.

Key words: low altitude penetration, safe flight space, trajectory planning, model improvement, smoothing cost
