| 摘 要： | 本文研究挠性空间飞行器姿态控制系统的时间域鲁棒稳定性分析,由于太阳帆板的转动和动量轮的转速变化,使飞行器的数学模型具有不确定性。这些不确定性可以归结为对动力学系统运动方程式的摄动。文中导出了鲁棒稳定性判据,并用算例说明其应用。

| Abstract: | The stability robustness of the attitude control system of a flexible spacetrafi in the time domain is investigated. As a result of the effect of the rotation of solar arrays and the variation of rotating speed of the momentum wheels, there is uncertainty in the mathematical model of the system. The uncertainty may be solved by the perturbation method to the motion equations of the dynamic system. The stability robustness criterion in the time domain is given. A numerical example shows the application of this method. |
