| 摘 要： | 敏感器输出的姿态信息和执行部件输出的力矩会因部件的实际物理特性夹杂着不同水平的噪声．噪声会对系统的姿态精度和稳定度产生一定程度的影响．采用布朗运动的微商描述测量随机噪声和力矩随机噪声，分别对卫星为刚体的情况和具有附件的情况进行分析，从而得出噪声对卫星姿态的影响关系．算例表明，存在随机噪声的情况下，挠性附件会降低卫星的姿态指向精度和稳态性能．

| Abstract: | The attitude information output by sensors and the moments output by actuators are often contaminated with noises induced by their actual physical characteristics. These noises bring some influence on the attitude pointing accuracy and the stability of the control system. In this paper the measurement and moment noise are modeled by using the differential quotient of Brownian motion. Then the influence is analyzed for a satellite as rigid body and a satellite with flexible appendages respectively. Moreover,... |
