Abstract
An asymptotic flight tracking controller is constructed by output regulation technology for hypersonic flight vehicles subjected to nonlinear non-minimum phase dynamic. The standard dynamic inversion technology cannot be utilized directly in control system design due to the unstable zero-dynamics in hypersonic flight vehicle. Hence, the output regulation theory is investigated to design a nonlinear asymptotic tracking controller in sinusoidal flight maneuver cases. Meanwhile, pseudo spectral technology is introduced to solve the center manifold equation in the standard output regulation problem. Finally, Numerical Simulation shows that the proposed control scheme can afford favorable tracking performance and suppress unstable zero dynamics effectively.
