| 摘 要： | 结合SINS／GPS／DVL组合导航系统各子系统的特点，提出了一种新的容错设计方案。此方案采用并列运行的滤波器族结构，该结构可以提供不受污染的最优解，且具有容错性好和系统输出数据热备份等优点。仿真结果表明，此方案既可有效地监测和隔离系统故障，同时保证了系统的精度。

| Abstract: | Based on the characteristics of subsystems of SINS/GPS/DVL integrated navigation system, a new fault tolerant scheme is provided, which uses parallel filters that can provide an uncorrupted optimal solution. It also has the advantages of good fault tolerance with hot-backup filters running at all times. The simulation results demonstrate that this scheme can not only detect and isolate system fault effectively, but also ensure the system accuracy. |
