| 中文摘要 |
| 本文针对卫星姿态确定系统, 提出了一种基于专用卡尔曼滤波器思想的陀螺故障诊断方法. 利用卫星姿态 运动方程设计了一种加性卡尔曼滤波器, 用于生成作为故障征兆信号的残差. 结合专用观测器思想和卡尔曼滤波 器, 提出了利用卡尔曼滤波器组的故障检测与分离律. 另外, 给出了一种基于3-σ的阈值计算方法, 用于设计故障诊 断中所用的检测阈值. 仿真结果验证了所提出方法的有效性. |
| 英文摘要 |
| A gyroscope fault diagnosis method based on dedicated Kalman filter scheme is proposed for satellite attitude determination systems. Based on the attitude kinematics, an additive Kalman filter is designed to generate residuals, which are used as the symptom of fault. By integrating dedicated observer scheme and Kalman filter, a fault detection and isolation method using a bank of Kalman filters is proposed. In addition, a 3-σ based method is presented to generate the threshold used in fault diagnosis. Simulation results are given to verify the effectiveness of the proposed method. |
