Design and Simulation of Aero Glide Beam Guidance System

The aero glide beam guidance system is an important radio wave guidance system in airplane auto land. Firstly, basic work principle of aero glide beam guidance system was brief discussed. Secondly, kinematic link and glide coupler in the glide beam guidance system were analyzed. The system structure of aero glide beam guidance system was designed. Lastly, a great deal of simulation studies were was done to design aero glide beam guidance system under the Matlab platform. Simulation results showed that the structure of designed aero glide beam guidance system was reasonable, and its control system was stability, and its steady state capability also got an improvement.
