| 中文摘要 |
| 在转动惯量存在不确定性时, 采用滑动模态控制方法对挠性航天器设计了姿态镇定控制律. 由于挠性模态是不可量测的, 首先设计了一个部分状态观测器对挠性模态进行估计. 进而结合滑模控制方法, 提出了基于观测器的滑模姿态控制律. 采用Lyapunov 方法证明了在存在转动惯量不确定性时, 所设计的滑模姿态控制律能使闭环航天器姿态系统稳定. 最后, 通过数值仿真例子验证了所提出方法的有效性. |
| 英文摘要 |
| In this paper, the sliding mode control technique is adopted to design attitude stabilization controllers for flexible spacecraft with inertia uncertainty. First, a partial state observer is designed to estimate the flexible modal variables since the flexible variables are unmeasurable. By using the sliding mode control technique, a
sliding mode control law based on observers is proposed for flexible spacecraft with inertia uncertainty.
The Lyapunov technique is utilized to show that the proposed sliding mode control law can stabilize the attitude system of the flexible spacecraft with the inertia uncertainty. Finally, a numerical example is employed to verify the effectiveness of
the presented control law. |
