| 摘 要： | 编队InSAR要求较高的相对姿态指向精度和地面观测重合度。根据相对姿态控制要求，提出了编队InSAR相对姿态计算的方法，从而确定从星的期望姿态。在此基础上，设计了两种非全状态反馈控制器及相应的角速度滤波器：半状态反馈控制器和角速度滤波器，输出反馈控制器和滤波器，进行相对姿态控制。数值仿真结果表明两种方法均可满足编队InSAR相对姿态控制要求。

| Abstract: | It is strict with the requirement of the pointing and superposition of observation area in ground for spacecraft formation InSAR.To satisfy the requirement,an approach computing the relative attitude is presented.And the expected attitude of the follower spacecraft is determined.Based on them,tow controllers are designed: semi-states feedback controller and output feedback controller as well as angular velocity filters.Simulation results show that two approaches can accomplish relative attitude control of spacecraft formation InSAR. |
