The mixed diagnosis algorithm of ANN and GA is introduced, and the structure and connection weight of neural network are optimized by double GA cycle. The computer flow chart of the hybrid method of ANN and GA is proposed. The three-layer feedforward neural network is used to perform the diagnostic functions. The application of the hybrid algorithm in fault diagnosis of a missile autopilot is also given.
