空间交会中多圈Lambert问题的算法改进与实现

针对目前多圈Lambert问题多种算法的不足之处,如精确性不高和难以编程实现等,利用问题解集的分布特点改进算法,编写可直接调用的Matlab程序,为多圈Lambert转移的拓展提供必要条件.以空间交会两动点间的轨道转移为例,建立二层优化的数学模型,并提出结合智能算法的解题思路.通过应用算例验证了程序的正确性和有效性.

Algorithm Improvement and Application for Loopy Lambert Problem in Space Rendezvous

Manifold algorithms on loopy Lambert problem have some limitation,such as low accuracy and hardly programming. By using the distribution characteristics of the solutions,the algorithm is improved.The achieved Matlab program can run at any moment,which offers the necessary condition for the development of loopy Lambert transfer. As an example,when two moving points rendezvous in space,a twolayer optimal model of transfer orbit is established and the corresponding solution is proposed combining with an intelligent algorithm. Finally,two application examples show that the program is correct and valid.
