In order to solve the anti-disturbance problem of aircraft landing control under strong disturbance, a design method of attitude and automatic throttle control law based on active disturbance rejection control method was given in this paper. In the active disturbance rejection control theory, if the nonlinear fal function is not smooth, the controller oscillation problem is induced at the subsection point, in this paper, the nonlinear function is reconstructed by using the continuous and derivable condition, by this method, the controller performance is improved. Taking a transport aircraft as an object, the automatic landing simulation is carried out under the condition of turbulence disturbance and parameter perturbation. The simulation results show that automatic landing control law designed by the active disturbance rejection method has good robustness.
