月球立方星姿态控制系统的初步设计与测试

立方星是一种模块化的微小卫星，在科学探测与专业人才培养等方面具有重要意义。针对目前立方星任务逐渐从近地轨道向深空扩展的发展趋势，以立方星月球深空任务为背景，利用商业器件设计并实现了初步的立方星姿态控制系统，以及姿态控制系统所必需的结构、电源、计算机等立方星子系统，同时给出了姿态测试平台的设计方案及其硬件实现。在所搭建硬件平台上，通过测量飞轮控制器的阻尼系数，对控制模型进行参数辨识与标定，获得了与数值仿真一致的实物测试结果。针对姿态控制系统设计了PD控制律，并在控制实验中实现了至任意姿态角的机动控制。

Preliminary design and test of attitude control system for lunar CubeSats

CubeSats are miniature functional satellites The increasing interest in CubeSats has uncovered the potential for planetary missions Besides, CubeSats is an excellent educational platform. The preliminary attitude control system is designed and the corresponding hardware is built using commercial products for a lunar mission employing a CubeSat constellation to provide positioning service for landers/rovers on the far side of the moon At the same time, the basic frame and necessary subsystems including the structure, power and on board computer subsystems, and the attitude experiment platform are constructed Based on the hardware platform, the control model is deeply understood through measuring damping coefficients by experiments A PD control method is designed to control the attitude The numerical and physical simulation results match well, and the CubeSat system achieves accurate attitude maneuver.
