Three Dimensional Trajectory Linearization Control for Flight of Air-breathing Hypersonic Vehicle

摘要：

　　An integrated guidance and control design approach for air-breathing hypersonic flight vehicle(ABHV)with strong aero-propulsion couplings and aerodynamic constraints is proposed in this paper.By exploiting the inherent nature of multi-time scale of hypersonic flight vehicle dynamics,the guidance and control system is designed based on time scales of subsystem dynamics,with the fast dynamics serving as the pseudo-control for the slow dynamics.Feedback gains are computed online as symbolic functions of the state variable along the reference trajectory,and no explicit gain scheduling or mode-switching is needed.Comparison with linear quadratic regulator control is conducted and performance of the proposed approach is demonstrated via high fidelity simulations with considerable aerodynamic uncertainty and environmental perturbation.
