New Fault Detection Structure and Algorithm Based on Federated Filter
Zhun Liu, Zhe Chen · Beijing Hangkong Hangtian Daxue xuebao · 2002
Based on federated Kalman filter, a new fault detection structure and algorithm was presented. The structure performs fault detection with the common states of local filters and reference filter. Chi square test and Elman neural network test algorithm were presented. As an application, comparisons for these algorithms are simple and reliable, these algorithms can detect the errors for both sensors and reference system, and have excellent fault tolerance performances, fast fault identifying and isolating ability.
