| 中文摘要 |
| 航天器空间电磁对接能避免诸如推进剂消耗、羽流污染和对接冲击等现有基于推力器对接所固有的缺陷, 应用前景广阔. 空间电磁对接控制目前国内外还没有有效研究, 论文主要针对此问题开展初步研究工作. 论文首先重点分析空间电磁对接特性及其主要控制问题, 然后采用反馈线性化方法对地面二维电磁对接控制模型进行线性化处理、以及基于线性化模型应用Kalman滤波方法估计电磁对接运动状态, 最后采用二阶稳定性方法设计控制律并进行仿真分析. 理论研究和仿真分析表明: 航天器空间电磁对接是可行的, 电磁对接非线性模型可以采用反馈线性化方法实现精确线性化, 基于线性化模型的二阶稳定性方法满足控制律设计要求. |
| 英文摘要 |
| The spatial electromagnetic docking will have favorable applications, because it avoids many disadvantages of the traditional thruster docking, such as the propellant consumption, plume contaminations and the docking impact. The control problems of the spatial electromagnetic docking haven’t been effectively solved; this article makes a preliminary
investigation at this point. First, the characteristics of the spatial electromagnetic(EM) docking are discussed, and the major control problems are analyzed. Secondly, the two-dimensional EM nonlinear model is linearized by using the feedback linearization technique, and the states of the resultant model are estimated by a Kalman filter. Thirdly, the docking controller is designed by using the second-order stabilization method and the simulation is also performed. Theoretical research and numerical simulation show the feasibility of the proposed method. |
