摘　　要：电推进行星捕获由于推力小,行星捕获时间将显著增长,具有与化学推进行星捕获完全不同的特性,极大地增加了轨道优化的难度。本文围绕小推力行星捕获段控制问题,以火星探测捕获轨迹优化问题为例,基于双曲轨道参数开展不同性能指标下行星捕获开关机及控制策略研究,使用间接法求解能量最优平面轨迹优化问题得到最优控制策略,并与沿速度方向反向的控制策略进行了比较。结果表明:所提方法实现了对小推力火星捕获的优化设计,捕获后轨道相较于目标轨道的误差较小,轨道安全性能够保证。Because of the low thrust,the time of planetary orbit insertion by electric propulsion has significantly increased.Electric propulsion has completely different characteristics from chemical propulsion,and greatly increases the difficulty in trajectory optimization.This paper focuses on the control problem of the low thrust trajectory of planetary orbit insertion phase,and takes the trajectory optimization problem of Mars orbit insertion as an example.Based on the hyperbolic orbit parameters,research is conducted on the switch and control strategies of planetary orbit insertion under different performance indicators.An indirect method is used to solve the energy-optimized plane trajectory optimization problem and obtain the optimal control strategy.The optimal control strategy is compared with the control strategy in the opposite direction along the velocity direction.The results indicate that the proposed method has achieved optimized design for low thrust Mars orbit insertion.The error in the captured orbit is smaller than that of the target orbit,and the orbital safety can be guaranteed.
