| 摘要: |
| 采用循环追踪算法解决编队航天器交会控制问题。建立并推导了线性循环追踪算法和非线性循环追踪算法数学模型，提出了绕飞平面采用循环追踪控制，绕飞平面法向采用比例微分进行振动抑制的编队交会控制律。基于脉冲推力方式，对绕飞平面分别采用线性和非线性循环追踪的三航天器编队交会控制问题进行了仿真分析。仿真结果表明，提出的基于循环追踪的控制方式可满足编队航天器交会控制要求，航天器按顺时针运行轨迹交会于初始位置决定的参考中心，三航天器间相对距离、相对运动速度变化趋势基本一致，速度增量消耗较小,为航天器编队构形控制研究提供有益参考。 |

| Abstract: |
| Rendezvous control of spacecraft formation based on cyclic pursuit algorithm is researched. The mathematical model of cyclic pursuit algorithm was established and deduced, and a new control law for spacecraft formation rendezvous was proposed, in which planar cyclic pursuit algorithm and normal proportional derivative method were combined. A rendezvous control for a formation by three spacecrafts adopting linear and nonlinear cyclic pursuit algorithm respectively is simulated. Simulation results show that, the proposed control law based on cyclic pursuit can meet the rendezvous requirement of spacecraft, spacecrafts rendezvous at the reference center determined by their initial position along clockwise trajectories, changing process of relative distance and relative velocity between them is consistent, and consumption of velocity gain is lesser. All this can provide theoretical reference for research of formation control for spacecrafts. |
