Abstract: A method using neural network with the hidden layer that consists of wavelets for flight control system identification was presented. A mother wavelet based on the sigmoid function was formed. A wavelet neural network (WNN) was designed using this function as nerve cell. WNN can identify the flight control system on-line. Simulation results about the application of this network were also given.

Key words: system identification, wavelet analysis, neural network, flight control system
