摘要
The longitudinal dynamics of hypersonic flight vehicles involves strong nonlinearity and coupling, uncertainties including parametric uncertainties, unmodeled uncertainties, external disturbances, and time-varying input and state time delays. In this paper, a robust controller design method is proposed for the longitudinal stabilization of these vehicles by the signal-compensation-based control idea. Theoretical analysis is given to prove the robustness properties of the designed closed-loop control system subject to multiple time-varying uncertainties and time-varying input and state delays. Simulation results are performed to show the validness and advantages of the proposed robust control approach.
