摘要：

针对星上相机运动干扰影响遥感卫星图像配准精度控制难题,研究基于磁浮控制力矩陀螺(magnetically suspended control moment gyros, MSCMG)的复合补偿控制提高图像配准精度的方法。以基于MSCMG作为执行机构,采用姿态反馈补偿控制方法,避免复杂的控制系统前馈补偿及其自身干扰,姿态稳定精度达到5.8×10-5(°)/s。在此基础上,提出了MSCMG姿态补偿控制与相机运动补偿算法一体化的复合补偿控制方法。仿真结果表明:采用一体化复合补偿控制,跟踪相机步进角精度由补偿前的6 μrad提高到补偿后的0.36 μrad,提高了一个数量级以上;扫描角精度由补偿前的0.6 μrad提高到补偿后的0.45 μrad;显著提高了相机光轴指向的稳定性;研究结果可为甚高精度遥感卫星高精度图像配准设计提供参考。

Abstract:

Focusing on improving image registration precision of the high precise remote sensing satellite due to the camera motion disturbance. The composite compensation method to improve the image registration based on magnetically suspended control moment gyros (MSCMG) is proposed. Firstly, the traditional attitude feedback control system avoiding the complexity of the feed forward control method and its disturbance is used in terms of MSCMG actuators, and the control attitude precision of to 5.8×10-5 (°)/s can be achieved. Then, the integration compensation method is put forward according to attitude control and camera pointing control in order to compensate the attitude residual error due to the constriction of the control band width of the control system. Finally, the simulation is done and the results show that not only the precision of elevation is improved from 6 μrad before compensated to 0.36 μrad after compensated, but also the precision of the scanning angle enhances as well from 0.6 μrad to 0.45 μrad, which boosts the pointing stability of bore sight evidently. Research results can be used as a reference for image registration design for the very high precised remote sensing satellites.
