Design and implementation of an operation system for lunar surface soil sampling & encapsulation

Abstract

<p indent=0mm>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.
