Anti-disturbance, continuous fixed-time controller is designed for faulted airbreathing hypersonic vehicle, including a fast fixed-time integral sliding surface (FFIS), a continuous fixed-time super-twisting-like reaching law (CFSTL) and a uniformly convergent observer. Firstly, the model of a hypersonic vehicle is established. Secondly, an FFIS is designed based on a newly presented fast fixed-time high-order regulator (FFTR). Then, a CFSTL is applied to drive the sliding mode vector and its derivative to achieve fixed-time convergence. Finally, lumped disturbances are estimated by a uniformly convergent observer.

Keywords: Air-breathing hypersonic vehicle, Disturbance observer, Fixed-time control, Sliding mode control.
