摘要
文中对 INS/GNSS/SAR 组合导航系统进行了系统级故障检测、隔离和重构技术研究。以惯导组合系统(INS/GNSS/SAR)为例,采用联邦滤波器的容错滤波算法,进行了计算机仿真,仿真结果表明:该算法具有不低于集中卡尔曼滤波的导航精度,同时还具有较强的容错性。
System Fault Detection,Isolation and Racofiguration of INS/GNSS/SAR integrated navigation system is stud- ied in this paper.The paper provides a fault-tolerant federated filter algorithm for INS/GNSS/SAR integrated naviga- tion system.The computer simulation demonstrates that its accuracy is equal to that of the centralized Kalman filter with the good performance of fault-tolerance.
