摘要
为确保嫦娥五号探测器月面无人采样封装任务的顺利实施,需要在有限的时间内操控航天器上复杂的采样封装机构和设备在不确知的环境中完成月面样品的采集和封装.为解决这一难题,本文提出了一种"近程验证-远程操控"的天地一体化双边型月面采样封装操控系统的设计方案,通过建立状态空间模型,推导并分析了系统的状态转移影响因素,给出了基于状态驱动的自主操控实施方法.验证试验证明,操控系统设计是正确有效的,在本操控系统的支持下,嫦娥五号顺利完成了我国首次月面无人采样封装任务.
To ensure the successful completion of the unmanned sampling and encapsulation mission of the Chang’e-5 lunar explorer, it is necessary to operate the complex mechanism and equipment on the spacecraft to complete the lunar soil sampling and encapsulation in the uncertain environment within a limited time. To solve this problem, this paper designed a "near verification-remote control"bilaterally integrated operation system;the state-space model was established, which deduces and analyzes the influence factors of the model state transition, and it proposed the autonomous control design based on states drive. Finally, through special verification tests,the correctness and effectiveness of the operating system design were demonstrated. Under the support of this operation system, the Chang’e-5 explorer completed the first unmanned lunar sampling and encapsulation mission in China.
