The invention provides a side wind resistance landing
flight track tracking control method based on side direction guide, which belongs to the
flight track tracking control technology of airplanes landed under the side wind condition. The
flight track tracking control method based on side direction guide is adopted, and comprises the following steps: calculating the inner ring posture control commands through a side direction guide law by the flight track tracking side direction deviation; generating steering engine control commands by an inner ring posture controller for controlling the
airplane posture; and calculating the current side direction deviation by the flight
line switching logics according to the current state of the
airplane for the side direction guide law calculation. A transverse side direction movement model of the
airplane is used for simulating the dynamic and kinematic model of the airplane. When being adopted, the side direction flight track
control system based on the
ground speed guide has better inhabitation effect on the side wind phenomena such as side direction gust wind, air turbulence, side direction
wind shear and the like when the airplane is landed. At the same time, the side direction flight
line switching logics can also meet the requirement of approach flight of the airplane under the side wind condition.
