| 摘 要： | 研究了卫星姿态控制系统故障诊断问题, 将滚动时域估计与交互式多模型(IMM)方法相结合, 利用滚动时域估计方法对系统状态进行估计, 系统转换概率也相应地利用了一个时间段的估计误差作为依据, 而不是只考虑一个时刻的估计误差, 因此有效减少了大噪声以及个别错误测量对诊断结果的影响. 最后的仿真结果证明了该算法的有效性.

| Abstract: | This paper studies the fault diagnosis problems of the satellite attitude control system. Since the satellite works in space,the attitude control system of satellite is easy to be effected by uncertainties and disturbances in the harsh working environment.Interacting Multiple Model(IMM) is one of the effective fault diagnosis methods of the satellite control system but it is subjected to strong noise or wrong data.For this reason,this paper proposes to combine the moving horizon estimation instead of the Ka... |
