摘要
利用低成本的微纳卫星组成星群协同执行空间任务,近年来引起了航天界的广泛关注.针对星群松散编队控制任务,将人工势场法和基于相对运动动力学方程的速度反馈控制相结合,在各颗卫星和目标之间构造吸引势场,在各颗卫星之间建立基于位置信息的避碰势场,在空间障碍物附近建立避障势场,同时引入速度反馈控制律,综合实现星群松散编队控制,并通过仿真算例验证了控制方法的有效性.
The application of low-cost micro-nano satellite clusters to perform space missions has drawn considerable attention in recent years.In this paper,the artificial potential field method is combined with the speed feedback control law based on the dynamics equations of relative motion for the loose formation control task of the satellite clusters.An attractive potential field is established between each satellite and the target.The inter-satellite collision avoidance potential field is established based on position information.The obstacle avoidance potential field is established near space obstacles.In addition,the speed feedback control law is adopted to comprehensively realize the loose formation control of satellite clusters.Some simulations are presented to verify the effectiveness of the proposed control method.
