摘要
本文引入了卫星太阳帆板反对称弯曲振动动力学方程,在此基础上分析了经典控制律下帆板的弹性振动情况。针对带有扰性太阳帆板卫星姿态控制系统设计中的帆板振动抑制问题,引入了H∞鲁棒控制理论,利用此理论设计了鲁棒控制器。仿真结果是此控制器很好地抑制了帆板振动。即H∞鲁棒的有效性显著。
In this paper, the antisymmetric flexure dynamics of satellites are introduced and the rigid body control law to flexible satellites is examined. In order to suppress the vibration of solar arrays, the H∞ rubust control methodology is applied to generate a robust control law. The conclusion is that the flexure vibration of satellites' two symmetric flexible solar arrays is well suppressed with this law. The simulation results are satisfactory.
