中文摘要: 考虑处于深空中的航天器网络编队的位置和姿态控制。控制目标是使整个编队中的航天器在控制器的作用下达到期望的位置和姿态,同时航天器编队趋于期望的队形和期望的相对姿态。采用基于图论的方法设计控制器,得到的控制器仅仅要求相邻的航天器之间保持信息交换,从而,和已有的研究中要求设计航天器两两通信的控制器相比,减少了整个航天器网络内部航天器间的通信;另外,得到的控制器不要求相邻航天器的速度和加速度的测量,从而减少了测量所带来的累积误差。数值仿真结果验证了控制策略的有效性。
Abstract:This paper considers the formation control and attitude control problems of networked spacecraft flying in deep space.The control objectives are to design a coupled controller under which each spacecraft can track its desired position and attitude and,simultaneously,the whole group move to the desired formation and achieve desired relative attitudes.The proposed controller obtained by graph approach,only requires information links with a spacecraft’s neighbors and therefore reduce the total communication costs of the whole formation compared to a previse study. In addition,the proposed controller requires no measurements of a spacecraft’s neighbor’s velocity and acceleration and therefore reduces the accumulative errors accompanying with measurements.Simulation results demonstrate the effectiveness of the proposed controller.
