卫星脉冲推力最优逃逸返回轨迹的非线性规划

重点研究了卫星通过轨道机动逃避碰撞、拦截并经一段时间后返回原轨道的逃逸方式。利用非线性规划理论建立了脉冲推力能量最省的逃逸轨迹规划模型，并考虑非球形摄动的影响对模型进行了修正。通过仿真验证了模型的正确性及求解的可行性，并分析了非球形摄动因素对逃逸过程的影响。

Optimal Impulse Satellite Evasion-Return Trajectory Planning Using Nonlinear Programming

The evasive-return maneuver had been studied, which is used for the satellite to avoid or evade the interception and collision in space. By using the nonlinear programming theory, a optimal impulse satellite evasive trajectory planning model considering earth oblateness perturbation had been established. Finally, the validity of the model and the effect of the perturbation on total fuel have been analyzed through the simulation results.
