A wavelet neural networks backsteppting method ( WNNBM) was designed for integrated guidance and control. First, the inte-grative control model of missile was built and simplified, the target kinematics characteristics and missile dynamics model of the system were combined, and guidance law and controller were put together. Controller was designed for integrative model by using backstepping method ( BSM) , in view of high degree of model simplification and uncertainty of unmodeled dynamics, wavelet neural networks ( WNN) in backstepping method was used. Finally, trajectory simulations were carried out and simulation results show the method can hit the target effectively and improve maneuverability and efficiency of missile.
