摘要
研究一类构形为中心刚体带挠性梁的航天器的平面大角度快速机动控制问题.推导了系统的非线性无穷维模型,设计了一种只利用中心刚体旋转角和角速度测量数据的模型跟踪控制方案,基于无穷维空间的LaSale不变原理,证明了相应闭环系统的渐近稳定性,并给出了物理实验结果验证所设计的控制算法的有效性.
This paper is concerned with the control for planar,large angle rapid slew maneuvering of a flexible spacecraft,consisting of a rigid central body and a flexible beam.A nonlinear infinite dimensional model of the system is derived.By using the measurements of the attitude angle of the rigid central body and its velocity only,a kind of model following control law is presented.Based upon the LaSalle's invariance principle in infinite dimensional spaces,it is shown that implementation of the control algorithm results in asymptotic stability of the closed loop system.Some experimental results are presented,showing the effectness of the designed control algorithm.
