研究了月面软着陆过程发生故障后的应急上升轨道,建立了整个应急上升过程的优化设计模型,并针对构建的强约束轨道优化问题,设计了将Gauss伪谱法和直接打靶法结合的混合优化策略,求解得到了满足应急条件的上升轨道参数。仿真分析表明该方法可以有效解决月面应急上升轨道优化问题,且求解收敛性和鲁棒性较好,可为同类问题的求解提供参考。 The emergency rise trajectory after lunar soft landing has been studied, and the optimal design model of the entire emergency ascent process has been established. In order to solve the problem of strong constrained orbit optimization, a hybrid method combining Gauss pseudo-spectral method and direct shooting method The strategy is optimized, and the ascending orbit parameters are obtained to meet the emergency conditions. Simulation results show that this method can effectively solve the lunar rising orbit rising problem, and the convergence and robustness of the solution are good, which can provide references for solving similar problems.
