针对未来小行星采样返回使命，提出了一种自主着陆导航与制导方案。提出了一种基于特征跟踪技术的自主导航方案，规划了具有初始和终端约束的期望下降着陆轨迹，以实现在小行星上的准时着陆，设计了基于误差相位分析法和PD + PWPF法的两种制导控制律，跟踪参考下降轨迹，并进行了仿真验证。最后通过计算机仿真验证了该方案的有效性。
This paper presents an autonomous landing navigation and guidance scheme for future asteroid sample return mission. An autonomous navigation scheme based on feature tracking technology is brought out firstly; secondly, desired descent landing trajectories with the initial and terminal constraints are planned in order to achieve arrive-at-time landing on an asteroid; then, two guidance control laws, based on error phase analysis method and PD plus PWPF method respectively, are designed to track reference descent trajectory; finally, the validity of the proposed scheme is confirmed by computer simulation.
