Abstract: In this paper, a novel flight control scheme is proposed by using the variable domain fuzzy control method. The proposed control strategy can improve control performance of near-space hypersonic vehicles (NHV) despite uncertainties and external disturbances. The control accuracy and anti-interference velocity are improved, and the calculated quantity is decreased by the change of fuzzy domain. To overcome the chattering phenomenon, the dynamic adaptive terminal sliding-mode control (TSMC) strategy is raised. The control law is designed by an intermediate auxiliary systems, step-by-step. Additionally, the Lyapunov method is used to prove that the tracking errors are converged in finite time.
