分布式遥感编队多星协同观测中的姿态控制
Attitude control in multi-satellite cooperative observations for distributed remote sensing
摘要
Abstract
This paper focuses on the cooperative observation problem in multiple spacecrafts.We first establish the desired attitude from the sun orientation to the target starting from the reference spacecraft.A proportional-differential (PD) controller is designed based on attitude and angular velocity deviations.Further, the Lyapunov theorem of the closed-loop system is introduced to prove the stability.Next, we establish the desired attitude for the follower spacecraft.To match the target positions in the image plane for the reference and follower spacecraft, a PD controller is proposed based on the difference of attitude between the reference and follower spacecraft.In addition, the Lyapunov stability of the closed-loop system is demonstrated.Finally, the simulation results show that the attitude control error between the reference and follower spacecraft is less than 0.01°, and the control accuracy satisfies the requirements of distributed remote sensing tasks.关键词
