For the hypersonic vehicle nonlinear attitude mode in reentry process with a strong coupling, aerodynamic parameter perturbations and non-deterministic, the hypersonic vehicle MIMO-ESO ADRC attitude controller is designed. Extended state observer and nonlinear law state error feedback are conbined, interference such as uncertainty, coupling and parameter perturbations as is put "the sum of interference", the extended state observer is used to estimate and dynamic feedback compensation, nonlinear law state error feedback is used to inhibit residual of compensation. ADRC controller is charged without a precise model of vehicle, and without precise perturbation boundaries of aerodynamic parameters. Simulation results show that the MIMO-ESO ADRC attitude controller can overcome the impact of large-scale perturbations of interference and aerodynamic parameters, have good dynamic qualities and tracking capabilities, also have strong robustness. It overcomes the difficulty of establishing accurate controlled model and obtaining parameter perturbation range in practical engineering, and has engineering application value.
