绳网拖曳带帆板失效卫星的波动控制

针对带有柔性太阳帆板的失效卫星，提出了一种基于波动控制理论的控制方法，同时实现了绳网拖曳过程中稳定碎片姿态与抑制帆板振动两个目标。首先，提出一种新的绳网简化结构，用Kane方法建立了动力学模型，使其能够在保证运算效率的同时具有更高的精度。然后，针对系统特性设计了波动控制策略，仅需要输入系绳张力的大小和方向，便能通过拖船位置的改变来消除失效卫星的自旋和帆板振动。最后，通过数值仿真验证了控制律的有效性。仿真结果表明，在控制律作用下的拖曳过程中，失效卫星的姿态能够快速稳定，同时帆板的振动也得到了良好的抑制。

Wave based Control for Tethered net Towing of Defunct Satellites with Solar Panels

For the defunct satellites with flexible solar panels, a wave based control method is proposed to realize the two objectives of debris attitude stabilization and solar panels vibration suppression during the tethered net towing. Firstly, a new simplified structure of the tethered net is proposed. The dynamic model established by the Kane method can not only ensure operation efficiency but also present high accuracy. Then, according to the characteristics of the system, a wave based control strategy is designed. Only by inputting the magnitude and direction of tether tension, the spin and panel vibration of the defunct satellite can be eliminated by changing the position of the tug. Finally, the effectiveness of the control law is verified by numerical simulations. The simulation results show that the attitude of the defunct satellite can be stabilized quickly, and the vibration of the panels can be suppressed very well.
