| 摘 要： | 本文研究在控制器能量受限条件下，一类挠性航天器旋转机动的控制问题。考虑刚性主体上带有挠性粱的航天器，并假定它在一平面内作旋转运动。本文针对航天控制工程中执行机构的工作模式，基于系统的无穷维模型，设计了简单易行的变结构控制方案，并证明了相应的闭环系统的渐近稳定性。数值仿真和物理实验结果显示了所设计的控制算法的有效性。

| Abstract: | This paper. deals with the siew maneuvering control problem; of a flexible spacecraft with constrained control.The spacecraft, consisting of a rigid central body and a .flexible beam, is assumed to perform planar mtoion,In accordance with the acting mode of the actuator in aerospace control enineering, and based on infulite dimensional model of the system, a kind of simple and easily implemented variable structure control law is presented, It is shown that implementation of the control algorithm results in asymptotic stability of the elosed-loop system, Some computer simulation and physical experimental reaults are presented, showing the effectnessof the control algorithm designed in this paper, |
