This study proposes an adaptive super-twisting sliding mode back-stepping controller (ASTSMBC) for hypersonic flight vehicles (HFVs) to hit maneuvering targets considering the impact angle constraint and autopilot dynamics. Firstly, a nonlinear longitudinal model of HFV is established, which formulates the relation between line-of-sight (LOS) angle and trajectory control variables. Then, an integrated guidance and control (IGC) scheme composing of back-stepping logic and sliding mode control technique is designed to guarantee the impact angle converge to the expected angle in finite time. Furthermore, the global stability of the closed-loop system is proved by utilizing the Lyapunov theory. Finally, numerical simulations demonstrate the effectiveness of the proposed scheme.
