| 摘 要： | 研究一类挠性多体航天器快速大角度机动的动力学与控制问题。考虑构形为“刚性主体 绕性梁 刚性端质量”的航天器，并假定它在一平面内作大角度旋转运动，本文利用Hamilton原理，建立了系统的非线性无穷维动力学模型，在只可测量刚性主体旋转角及其速率的情况下，设计了一种线性反馈控制方案，并证明了相应的闭环系统的渐近稳定性。

| Abstract: | This paper is concerned wish the dynamics and control for planar, large anglerapid slew maneuvering of a flexible multi - body spacecraft, consisting of a rigid centralbody, a flexible beam and a rigid tip mass. Nonlinear infinite dimensional model of the sys-tem is derived by employing the Hamilton's principle. By using the measurements of the atti-tude angle of the rigid central body and its angular rate only, a kind of linear feedback con-trol law is presented. It is shown that implementation of the control algorithm results inasymptotic stability of the closed - loop system . |
