Abstract For its outstanding aerodynamic capabilities, the integrated design of the waverider and inlet is widely accepted in hypersonic aircraft. Three aspects of the integrated design of the waverider and inlet since 2020 are mainly described in th

As a hypersonic aerodynamic configuration that can break through the lift-drag ratio barrier, waverider configuration is an important candidate for wide-speed reusable aircraft. Therefore. It has become a hot research topic that improving the low spe

This paper proposes a fixed-time backstepping control method based on a disturbance observer for a hypersonic morphing waverider (HMW). Firstly, considering the disturbance of attitude channels, a dynamic model of a variable-span-wing HMW considering

Aiming at the defect that traditional PPC usually leads to control singularity when dealing with the input constrained problem, a new non-fragile prescribed performance control (PPC) methodology is proposed based on neural approximation for waverider
