摘要
提出了采用自适应加权和卡尔曼滤波相结合的自适应滤波方法进行组合导航系统级故障检测的新思路,该方法不仅可以判断出故障是否出现,而且可以对故障量的值进行跟踪估计,在估计的同时可以判断故障值出现在哪一个量测通道中。SINS/GPS组合导航系统故障检测和隔离的系统仿真结果验证了本算法的有效性。
Adaptive estimation, a new approach of local system failure detection of tolerant navigation system is proposed in this paper. It is a way not only can detect the failure but also can estimate the failure value and at the same time isolate the fail component. Directing toward the SINS/GPS system, the fault detection simulation is carried out with the approach, and a good result is achieved.
