| 摘 要： | 对目标机动条件下的定点伴飞控制进行了研究。根据相对运动关系,建立适于伴飞模式的相对运动方程,将目标机动大小作为未知量加入相对运动方程,构建不确定系统。用LQR和Lyapunov法结合的方式设计相应定点伴飞控制律。理论证明了在目标机动时该控制律仍能实现系统的渐近稳定。仿真结果验证了该控制律的有效性。

| Abstract: | A control approach for station keeping with maneuver target was studied in this paper.The relative dynamic equations which were suitable for station-keeping mode were derived according to the relative motion of two satellites.The uncertain system was constructed with the unknown maneuver acceleration of the target included in the relative dynamics.Based on the uncertain system,the station-keeping control law which combined LQR and Lyapunov approach was designed.The uncertain system with maneuver target was proved to be asymptotically stable using this control law.The simulation result validated the effect of the control law. |
