Backstepping control method is a new way for developing the nonlinear system. It can solve non-linearity, coupling and uncertainty of system. In this paper, a three-dimensional missile mathematic model is established and the three-channel control system law is designed. According to aerodynamic uncertainties, the robustness of system is analyzed. The validity and robustness of missile flight control system are proven by simulation with MATLAB based on backstepping control method. The simulation results indicate that the backstepping control method is an effective nonlinear control measurement.
