The adaptive flight control technique, feedback linearization and model inverse theory are reviewed. The error dynamic characteristics are analyzed and an adaptive neural network attitude control system is designed. Among them, the model inverse based on the hovering state, adaptive control law based on neural network to ensure that the tracking error and control signal bounded. The simulation results show that the model inversely enhanced nonlinear neural network can adapt to the uncertainty and modeling error of the unmanned helicopter. Moreover, the simulation results of PD controller and robust coefficient changes are compared
