To improve the super maneuver flight control performance with model uncertainty, a super maneuver flight control law design method based on auto disturbance rejection backstepping control is approved in this paper. The high angle of attack six-DOF nonlinear airplane model is established. Based on the backsteppint design method, the steady flight control ability for nonlinear airplane model is realized. For model uncertainty, the extend state observer of the auto disturbance rejection control is used to observe the modeling error and online compensate. The super maneuver flight digital simulation results show that the controller has high angle of attack control ability with 40% model error. The auto disturbance rejection backstepping nonlinear control method has good super maneuver fight control performance.
