摘要
以编队卫星激光通信为背景,在已知主从星之间的相对位置和姿态的情况下,提出了一种卫星编队完全分布式协同控制策略,设计了一种分布式相对姿态变结构协同控制律,并利用Lyapunov稳定性原理证明了该控制律能够保证编队的全局渐进稳定。仿真结果表明,在编队卫星受到各种干扰力矩影响时,该方法能够有效提高编队卫星相对姿态控制精度,从而实现编队卫星之间的姿态协同,证明了所设计控制器的有效性。
Under the background of mission on laser communication by formation flying satellites and the assumption of known relative position and attitude, a fully decentralized variable structure relative attitude coordination control strategy with the proof of global stability using a Lyapunov function was given. Simulation results indicate that the proposed method can minimize relative attitude error in the presence of disturbance acting on the satellites in the formation, achieve attitude coordination among the satellites and demonstrate validity of this control strategy.
