摘要：
Two integrated guidance and control methods based on dynamic surface control theory are designed for flexible hypersonic vehicles in glide phase. The longitude translational and rotational equations of flexible hypersonic vehicles in glide phase are denoted. A strict-feedback integrated guidance and control design model for flexible hypersonic vehicles is deduced. The flexible states of the hypersonic vehicle are regarded as uncertainties. Two integrated guidance and control schemes are proposed based on adaptive approach and nonlinear disturbance observer (NDO) technique, respectively. The states of the closed-loop systems are proved to be uniformly ultimately bounded based on Lyapunov stability theorem. Simulation experiments are conducted to verify the effectiveness and robustness of the proposed schemes. The performance differences between the two schemes and the reasons behind are analyzed further. © 2022, Editorial Office of Systems Engineering and Electronics. All right reserved.
