Fault Prognosis Modeling of Aviation Electronic System Based on Kalman Filtering

According to characteristics of fault in aviation electronic system, first of all, fault prognosis model based on Kalman filtering is established and analyzed in this paper, a certain method of to determine fault point critical status value is given, and then a project for fault prognosis is decided and fault prognosis algorithm is designed. And at last, historical data in system operation and test is fully utilized by fault prognosis model, and by so doing a theoretical foundation is provided for predicting fault and performance.
