摘要:
未来的月球着陆任务将着力于开发月球资源、建立月球基地,这些都离不开月球软着陆技术的支持;而要实现探测器在预选点安全精确地着陆,就离不开动力下降制导控制技术的支持。本文系统地总结了两种成功的月球软着陆及其制导方式,对已有的制导控制方案及其研究进展进行了详细的阐述和对比分析。以未来的月球采样返回和月球基地任务为潜在工程目标,对下一代的月球软着陆动力下降的制导控制及其所涉及的关键科学技术问题进行了比较全面的分析和展望。

Abstract:
Future lunar landing missions substantially focus on lunar resources and moon base, which lead to high-precision requirements for landing on the moon. And to achieve safe pin-point landing at a pre-selected landing site, the powered descent guidance and control technologies are of great importance for these missions. First, in this paper, two successful lunar soft landing scenarios and corresponding guidance modes are summarized systematically. Second, the existing lunar soft-landing guidance schemes and state-of-art are specifically described and comparatively analyzed. Finally, taking future sample return and moon base missions for potential project goals, a comprehensive analysis and prospect for next generation powered descent guidance and control technologies and the related core scientific and technological problems for lunar soft landing are conducted.
