| 中文摘要:以低轨环境下无拖曳卫星控制器设计为研究对象，对于给定结构的无拖曳卫星，考虑推进器增益存在不确定时的鲁棒控制器设计。首先，简要介绍无拖曳卫星的概念及原理；之后，对带有不确定性的无拖曳卫星控制系统进行分析与建模，并对其进行LFT不确定性建模，最后利用μ分析和D-K迭代设计出满足鲁棒性能的鲁棒控制器。仿真结果说明鲁棒控制器的有效性。 |

| Abstract:The paper presents a robust controller for lower-earth-orbit drag-free satellite with given structure. First, a brief introduction to the drag-free satellite is given, then the Drag-Free control system is analyzed and modeled, by which LFT uncertainty model is established. With μ synthesis and D-K iteration, the robust controller can be proposed. The simulation results are presented to illustrate the effectiveness of the method. |
