Since the nonlinear model of guided projectile has uncertain aerodynamic parameters, modeling errors and external input interference, a robust adaptive controller was designed for the guided projectile based on dynamic surface.The problem of “explosion of complexity” in traditional backstepping approach was solved by introducing the first-order low pass filters and obtaining the differential of the virtual control inputs.The effect of uncertain parameters of the model was cancelled out by the robust function, and the external disturbances was eliminated with the nonlinear damping items.Finally, the closed-loop system was proved by Lyapunov function to be semi-global stability.The design method is simple and the limiting conditions of uncertainty was relaxed while making effective use of the given information, and the trajectory error can be adjusted by the parameters of controller.Simulation results show the availability of this method.
