摘要：
Considering the underactuated hypersonic flight vehicles with strong uncertainty of the dual channel attitude control strategy, practical feedback-based dual-channel control schemes are given and the robustness analysis method based on the bounded perturbation analysis of eigenvalues is proposed. Firstly, two control schemes, namely the pole-assignment schemes and modes-decoupling scheme, are given to improve Dutch roll dynamics based on the approximate linearization approach and engineering constraints. Then, to evaluate the robustness of the closed-loop system for the uncertain parameters, the eigenvalue sensitivity matrix, the eigenvalue bounded-perturbation-matrix and eigenvalue bounded-perturbation index are proposed. Finally, simulations and analysis of the proposed schemes and methods are given based on the closed-loop six degree-of-freedom model with nominal parameters and perturbed parameters, respectively. Simulation results demonstrate that both schemes could solve the dual-channel control issue. The results also show that the perturbation analysis of eigenvalues could precisely evaluate the system robustness. © 2022 Beijing University of Aeronautics and Astronautics (BUAA).
