Abstract: The flying wing unmanned aerial vehicle(UVA) has poor maneuvering capacity, strong nonlinear and coupling capacities. The traditional Backstepping method can improve the system robustness of flying wing UVA, but has the problems of singular value calculation and conservative property. An improved Backstepping method is proposed. The nonlinear radiation model of flying wing UVA is established. The method is used to perform the robustness controller design, and the controller is verified with simulation analysis. The results show that the method can solve the problems of singular value calculation and conservative property of traditional Backstepping method, break the limitation of current robust design methods whose upper bound of uncertainty norm is known, and the designed controller has high robustness.
