使用基于李亚普诺夫的控制方法,研究了双星编队飞行系统的相对姿态控制问题.考虑角速度可测和角速度信息不可测量两种情况,进行了状态反馈和输出反馈的姿态控制算法的设计,并通过李亚普诺夫方法证明了编队飞行系统全局渐近稳定性.最后对给出的算法进行了数值仿真.结果表明,所设计的控制算法实现了编队卫星之间的姿态协同控制,是可行的、有效的.
This paper investigates the problem of relative attitude control of a two-satellite formation using Lyapunov-based methods.Considering the measurability and immeasurability of angular velocity,we develop the state feedback control and output feedback control schemes.Global convergences of the satellite formation are proven mathematically.Finally,simulations are performed.Results demonstrate that the attitude coordination among the satellites can be achieved,which shows that the proposed schemes are effective and feasible.
