摘要
翼伞是一种对外部环境敏感性高的飞行器,在翼伞航迹规划中,需要考虑到风速和风向的变化以及地形高度的变化等因素来规划最优航迹.论文根据翼伞质点模型,对航迹规划中的约束进行数字化处理,包括风场、地形、威胁区、转弯半径等约束;将原始自然算法应用于翼伞航迹规划中并仿真验证了算法的合理性.相比于传统的航迹规划方法,基于原始自然算法的翼伞航迹规划技术具有更高的效率和更好的安全性,可以同时考虑多种外部因素干扰,以更好地适应不同的飞行环境.
Abstract
Parafoil is a highly sensitive aircraft to the external environment.In parafoil path planning,various factors such as changes in wind speed and direction,as well as changes in terrain height,need to be considered to plan the optimal path.This arti-cle digitizes the constraints in path planning based on the parafoil point-mass model,including constraints such as wind fields,ter-rain,threat zones,and turning radii.The original natural algorithm is applied to parafoil path planning,and the rationality of the al-gorithm is verified through simulation.Compared with traditional path planning methods,the parafoil path planning method based on the original natural algorithm has higher efficiency and better safety,as it can simultaneously consider multiple external factors of interference to better adapt to different flight environments.
