摘　　要：结合UKF滤波器和Huber滤波器各自的优点,设计了用于空间编队飞行的Huber-UKF相对导航滤波器,该滤波器在测量误差不完全满足高斯分布或含有粗差情况下具有较好的鲁棒性.另外,考虑到追踪航天器可能距离目标航天器在较近距离进行编队飞行,从安全性角度出发,对追踪航天器的轨控加速度偏差进行了建模,基于Twisting算法设计了对推力故障具有一定容忍度的二阶滑模变结构控制器,该控制算法计算简单,具有工程参考价值.Based on Unscented filtering method and Huber robust filtering method, an adaptive robust relative navigation HuberoUKF filter is obtained. Besides, the second-order sliding model control in terms of the twist algorithm is used to design the relative orbital controller and the robustness of the system is increased. Simulation results demonstrate the relative navigation method and relative orbital control algorithm are applied to the precise formation flying with the target on elliptical orbit and are robust to the thrust fault of the chase spacecraft.
