| 摘 要： | 提出一种组合导航信息融合新方法,该方法能提高容错性能,更好地进行故障检测、隔离和重构.同时,当故障发生时,由于融合了系统信息,它能使重构的系统以更高的精度工作.采用这种滤波器设计了捷联惯导系统、GPS、多普勒雷达三传感器信息容错系统.仿真结果表明, 这种设计方法对陀螺、加速度计、GPS、多普勒雷达的软故障是有效的.

| Abstract: | This paper presents a new information fusion filter in integrated navigation. The method can improve the fault-tolerant performance and make well fault detection, isolation and reconfiguration of the integrated navigation system exist. Based on three sensors'(strapdown system, GPS receiver, Doppler radar) information fusion, a fault-tolerant navigation system is designed with this information fusion filter and two-ellipsoid overlap test. Simulation results show that the design is efficient with the soft-failure of gyro, accelerator, GPS receiver and Doppler radar. |
