摘　　要：This paper investigates the state-constrained controller design of a hypersonic flight vehicle(HFV)based on an asymmetric barrier Lyapunov function(ABLF).The robust adaptive back-stepping controller with integral terms is applied for the HFV longitudinal dynamics.Considering the asymmetric angle of attack(AOA)constraint caused by the unique structure and scramjet,the controller is modified by constructing an ABLF,where the asymmetric constraint on AOA tracking error is introduced.Combined with the constraint on virtual control,the AOA is restricted to a predefined asymmetric interval.The system stability and the AOA constraint are guaranteed via Lyapunov analysis.Simulation results verify that the AOA can be kept in the given asymmetric interval while the altitude reference signal is tracked.
