摘　　要：This paper concerns the exponential attitude-orbit coordinated control problems for gravitational-wave detection formation spacecraft systems.Notably,the large-scale communication delays resulting from oversized inter-satellite distance of space-based laser interferometers are first modeled.Subject to the delayed communication behaviors,a new delay-dependent attitude-orbit coordinated controller is designed.Moreover,by reconstructing the less conservative Lyapunov-Krasovskii functional and free-weight matrices,sufficient criteria are derived to ensure the exponential stability of the closed-loop relative translation and attitude error system.Finally,a simulation example is employed to illustrate the numerical validity of the proposed controller for in-orbit detection missions.研究了引力波探测编队航天器系统的指数收敛姿轨协同控制问题。首先,对天基激光干涉仪星间距离过大导致的大规模通信时延进行了建模。然后,面向通信时延的影响,设计了一种基于时延信息的姿轨协同控制器。此外,通过重建保守性较小的Lyapunov-Krasovskii函数和自由权重矩阵,推导出保证闭环相对位姿误差系统指数稳定的充分条件。最后,通过仿真算例验证了设计的控制器在引力波探测任务中的有效性。
