| Abstract: | A fault diagnosis system of flight control based on the wavelet neural network was introduced. A mother wavelet based on the sigmoid function was formed. A wavelet neural network was designed using this function as nerve cell. Three kinds of common faults of flight control system can be distinguished by this network. Simulation results about application of this network were also given. |
