【摘要】 针对遥感卫星对地凝视成像的姿态控制问题,提出了一种适应任务需求的姿态控制方法。该方法采用分段结构:一阶段基于Bang-Bang控制,使卫星姿态快速指向地面目标;二阶段采用级联方法设计自适应控制器,实现卫星持续高精度的姿态跟踪控制。最后通过仿真试验,验证了所设计姿态控制方法的有效性。更多还原

【Abstract】 Aiming at the attitude control problem of remote sensing satellite’s earth staring imaging, this paper proposes an attitude control method to meet the requirements of the mission. The method adopts a piecewise structure: firstly, based on Bang-Bang control, the satellite attitude points to the ground target quickly; secondly, an adaptive controller based on cascade method is designed to realize the continuous and high-precision attitude tracking. Finally, the effectiveness of the proposed method is verified by simulation analysis.更多还原
