Abstract—The interval type-2 fuzzy, combined with sliding mode control, is proposed in this paper to design a novel nonlinear robust controller for a hypersonic aircraft. In this method, sliding mode reaching law is designed to keep the system stable. In order to overcome the uncertain parameters and external disturbances which exist in aerospace, we utilize an interval type-2 fuzzy approach represented by 9-point representation. Simulation results indicate that this method of interval type-2 fuzzy sliding mode controller can provide robust flight control to ensure good tracking performance of hypersonic aircraft.
