标题： A Robust Periodic Controller for Spacecraft Attitude Tracking

摘要： 本文提出了一种新颖的方法，用于卫星的鲁棒周期姿态控制。 在合成中尊重卫星动力学的周期性，可以实现在轨道上的恒定性能和鲁棒性要求。 所提出的设计采用了一种物理动机加权方案的混合灵敏度控制设计。 控制器使用一种新颖的结构化线性时变输出反馈合成方法计算，该方法保证了最优的L2性能。 该合成方法是一个凸优化问题，并避免了经典周期H-infinity合成中固有的耦合条件的逐网格评估。 此外，控制器具有透明且易于实现的结构。 使用一个太阳能发电站卫星来证明所提出方法在周期性卫星姿态控制中的有效性。 显示英文摘要

摘要： This paper presents a novel approach for robust periodic attitude control of satellites. Respecting the periodicity of the satellite dynamics in the synthesis allows to achieve constant performance and robustness requirements over the orbit. The proposed design follows a mixed sensitivity control design employing a physically motivated weighting scheme. The controller is calculated using a novel structured linear time-periodic output feedback synthesis with guaranteed optimal L2-performance. The synthesis poses a convex optimization problem and avoids grid-wise evaluations of coupling conditions inherent for classical periodic H-infinity-synthesis. Moreover, the controller has a transparent and easy to implement structure. A solar power plant satellite is used to demonstrate the effectiveness of the proposed method for periodic satellite attitude control.
