| 摘 要： | 针对卫星编队飞行相对位置协同控制问题，基于编队卫星相对运动非线性动力学方程和一致性理论设计了两种自适应协同控制器。首先，在卫星质量不确定和星间信息交互存在通信时延的条件下，设计了一种全状态反馈自适应协同控制器，并证明了该控制策略对空间摄动力的鲁棒性。其次，进一步考虑速度信息不可测的条件下，采用滤波器设计了一种无速度反馈的自适应协同控制器。最后，以编队构型重构为例对两种自适应协同控制器进行了仿真校验。仿真结果表明：两种自适应协同控制器均可有效应用于卫星编队飞行相对位置的协同控制，能够保证编队卫星对各自期望轨迹跟踪的同时暂态保持编队构型的稳定，具有较高的控制精度。

| Abstract: | Aiming at the relative position cooperative control problem of satellite formation flying, two adaptive cooperative controllers are designed based on the nonlinear dynamics equation of formation satellite relative motion and consensus theory. Firstly, under the condition of satellite mass uncertainty and communication delay, a full sate feedback adaptive cooperative controller is designed, and its robustness to space perturbations is proved. Then, the condition of velocity-free measurement is considered, a velocity-free feedback adaptive cooperative controller is designed by utilizing a filter. Lastly, the formation reconfiguration is simulated by using the two adaptive cooperative controllers. The results show that the two adaptive cooperative controllers can be effectively applied to the satellite formation cooperative control, and can guarantee the satellites track to the desired trajectory as well as the instantaneous stability of formation shape at high control accuracy. |
