摘要
在限制性多体问题下的行星际转移轨道是一个典型的两点边值问题。求解该类问题的常用方法是采用打靶法结合Runge-Kutta积分进行求解,但是在求解行星际转移轨道时,由于方程比较复杂普通的打靶法在某些情况下不能求到解。文章提出了一种基于差分演化和打靶法的混合算法可以很好地解决这些问题。
Solving the interplanetary transfer trajectory of spacecraft in multibody system,can be transformed into a two-point boundary value problem.To solving the problem shooting method and Runge-Kutta method were used for the numerical integration,and the state transfer matrix was used for a differential correction.But the problem is too complex that using the traditional method is very difficult or impossibility to compute the result.In this paper we propose using an hybrid methodto solve the problem.
