| 摘 要： | 针对由飞轮等星上高速旋转部件所引起的高频姿态和指向抖动,提出一种基于磁流体动力学特性的角位移敏感器用于星上高精度宽带宽的微振动测量,以弥补常规姿态测量系统测量频带低,动态范围有限的缺点.介绍以扩展姿态确定带宽为基础的高精度姿态确定方法.给出了以陀螺、星敏及ADS测量信息为基础的宽带宽的姿态确定方法及系统的模型,采用了卡尔曼滤波来确定卫星姿态.仿真分析结果表明存在高频姿态抖动的情况下,宽带宽的姿态确定方法的估计精度优于传统的姿态确定方法,由此验证了宽带宽的姿态确定方法的有效性及精确性.

| Abstract: | According to the high-frequency attitude and pointing jitter that caused by reaction wheel,an angular displacement sensor(ADS) based on the magneto hydrodynamic effect is proposed to measure high-frequency attitude jitter information which conventional attitude sensors can not provide.The technique of attitude estimate based on the extended attitude determination bandwidth is introduced in this paper.The model of the system combined with gyro,star sensor and ADS is built,and the Kalman filter is used to det... |
