摘要

In this paper, the flight simulation and control of a flying-wing aircraft in landing is presented. Significant dynamic nonlinearity and atmospheric disturbance are main problems for a flying-wing aircraft in landing phase. Therefore, a nonlinear controller with strong robustness is required. Active disturbance rejection control technique is used to design the controller which could estimate and compensate the uncertainties. A landing condition in which the wind shear encounters and ground effect before touchdown is considered, and a nonlinear longitudinal dynamic model of flying-wing aircraft in variable wind field is established. Simulations are conducted in MATLAB and the controller is shown to suppress the wind effects and ground proximity.
