摘　　要：为了实现在轨卫星姿态控制系统中陀螺仪的故障检测,设计基于滑窗最小二乘的检测算法。算法在无需额外敏感器辅助前提下,通过监测三轴陀螺仪两两测量差值的多项式拟合系数的幅值和方差变化趋势,准确获得陀螺仪发生故障类型及时间。仿真结果表明,算法能够检测出多种故障模式,具有很好的工程应用价值。In order to accomplish the fault detection for gyroscope mounted to the satellite altitude control system which is on orbit,this paper designs an algorithm based on the sliding window least square method.Without the help of additional sensors,this algorithm monitors the variation trend of polynomial fitting coefficients' amplitude and variance from the measurement difference of two gyroscopes which can determine the fault type and fault time.Simulation results show that this algorithm can detect multiple fault types and has great engineering application value.
