The invention provides an auto-disturbance rejection controller design method for hypersonic flight vehicle data packet loss, which comprises the following steps: establishing a first data transmission model of a hypersonic flight vehicle under the condition of incomplete data transmission based on an initial data transmission model of the hypersonic flight vehicle; adding a closed-loop state feedback system into the first data transmission model to obtain a second data transmission model; performing system stability analysis on the second data transmission model, and calculating a feedback gain coefficient of the closed-loop state feedback system; based on the feedback gain coefficient and a second data transmission model, determining a transfer function of elevator input and attack angle output of the hypersonic flight vehicle; and designing an active disturbance rejection controller of the hypersonic flight vehicle based on the transfer function. The technical problems that in the prior art, interference errors cannot be estimated, and robustness is poor are solved.
