The simulation results indicate that the proposed switch control method can fly in either endoatmosphere or exoatmosphere and has a good robustness. 仿真实验表明，采用切换控制方法所设计的姿控系统可以适应大气层内外飞行，鲁棒性较强。
In this paper the optimal rendezvous guidance laws of the exoatmosphere are investigated by using the optimal control theory. 本文应用最优控制理论讨论了外层空间的最优交会制导问题。
