摘要
为了解决飞行器回收归航精度问题,提出一种基于人工鱼群算法的飞行器归航轨迹方法。根据飞行器飞行特性,建立飞行器-翼伞组合体六自由度模型,将整个归航轨迹划分为开伞阶段、径向飞行、盘旋调整、目标对准和雀降五个过程。根据着陆目标要求建立目标函数,将航迹规划问题转化为参数寻优问题,并采用人工鱼群算法对归航过程关键参数寻优求解,设计出一条易于实现控制又兼顾能量损耗的归航轨迹。
According to the flight characteristics of the spacecraft,the six-DOF model of the spacecraft-parafoil is established,and the whole homing trajectory is divided into parachute opening phase,radial flight,spiral adjustment,target alignment and descent phase.The objective function is established according to the objective requirements to transform the track planning problem into a parameter optimization problem,and the artificial fish swarm algorithm is used to solve the homing process parameters,so as to design a homing trajectory which is easy to realize control and reduce energy.
