Research of FDI for Artificial Neural Network Failure Detection Method Based on Model Residual

摘要

FDI （Failure detection and isolation ）is widely used in field of flight control, because the failure detection method base on mathematic model has the shortness that the precision of the failure detection method based on linear model depends on accuracy of the mathematic model in some degree, the FDI method based on neural network overcomes this shortness. In this paper hierarchy neural network is used to simply the structure of network and improve the performance of network according to the failure tree analysis and the research based on neural network FDI method to one kind UAV is done. Simulation in MATLAB is done to testify to this method.
