| 摘 要： | 提出了一种航天器附着（软着陆）小行星的制导与控制规律。为了保证垂直软着陆，事先规划了满足约束的理想视线与视线角轨迹，通过设计滑模变结构控制器跟踪理想轨迹，实现了在小行星表面垂直软着陆；证明了制导与控制规律的鲁棒性；最后通过数学仿真验证了提出的制导与控制规律的可行性。

| Abstract: | A guidance and control strategy for attaching a vehicle to a small solar system body is presented. In order to ensure soft-landing, a prescribed line of sight and angle of sight profile satisfying restriction are planned, a sliding mode controller is designed to track the prescribed line of sight and angle of sight profile for safely soft-landing on surface of small asteroid. The robust feature of the close-loop guidance scheme is stressed. Finally, numerical simulations are conducted to verify that the given guidance and control strategy is feasible. |
