Fault detection in flight control systems via innovation sequence of Kalman filter

摘要: In the paper, an approach based on ratio of two quadratic forms which matrices are theoretic and selected covariance Kalman filter innovation sequence for sensor fault detection, is presented. The optimal arguments found to quickly detect faults in sensors. does not require a priori information about statistical characteristics system. Although approach, like other detection approaches sequence, cannot isolate faults, it quite useful considerably affecting will be augmented faults.
