摘　　要：利用非线性规划方法研究了多脉冲最优轨道交会问题,考虑地球扁率J_2摄动影响,建立普遍适用的空间飞行器数学模型。以迭代的方法确定空间预定交会点,在此基础上建立了用于求解多脉冲最优轨道交会的非线性规划模型,并对双脉冲固定时间交会轨道进行优化,得到了最优速度增量的大小、方向和作用时间,通过仿真与Lambert轨道规划方法进行比较,验证了此方法的有效性和优越性。In this paper,the problem of multi-pulse optimal orbit interception is studied by means of nonlinear programming method,and the universally applicable mathematic model of the space vehicle is established by considering the influence of the oblateness of the Earth’s flattening J 2.The space predictive interception is determined by iteration.Based on this,a nonlinear programming model for solving the multi-pulse optimal orbit is established and the two-pulse fixed-time interception orbit is optimized to obtain the optimal speed increment size,direction and time of action.Compared with the Lambert orbit planning method through simulation,the validity and superiority of this method are verified.
