以Hill方程为基础对圆轨道近距离双脉冲绕飞优化问题进行研究.首先给出双脉冲绕飞的优化模型并推导分析得出待优化的变量,同时构造了燃耗和时间加权的性能指标函数并考虑安全约束,然后设计了粒子群优化算法对绕飞过程进行优化,最后通过对-V-bar到+V-bar、+R-bar、+H-bar的绕飞进行仿真获得燃耗和时间加权最优的安全绕飞轨迹,与遍历寻优结果一致,由此验证了粒子群优化算法的有效性.
Based on the Hill equation, the optimization problem of circular orbital double-pulse around-the-fly is studied.Firstly, the optimization model of double-pulse around-the-fly is given and the variables to be optimized are deduced and analyzed, and the performance indexes of fuel consumption and time-weighted Function and considering the safety constraints, and then design a particle swarm optimization algorithm to optimize the process of winding around the fly, and finally get the fuel consumption by simulating the flight around -V-bar to + V-bar, + R-bar and + H-bar And the time-weighted safest fly-around trajectory are consistent with the results of traversal optimization, which verifies the effectiveness of PSO.
