In order to solve the problem of high lift to drag ratio configuration of hypersonic vehicle and strong coupling of three channels in maneuvering flight, whole-channel decoupling control method based on extended state observer is proposed. This method does not need to design the coupling compensation model according to the characteristics of the coupling term, but regards the coupling term in the hypersonic vehicle channel as the disturbance term. Through the design of the extended state observer, which has the ability to track and estimate the disturbance in real time, the coupling disturbance will be estimated, compensation control is used to eliminate the influence of coupling, the decoupling control is completed. Furthermore, the LQR control method is used to design the closed-loop feedback control law of the attitude control system.Finally, a practical decoupling control method for hypersonic vehicle engineering is realized, the correctness and effectiveness of the control method is verified by mathematical simulation.
