Attack-of-Angle Convergence Control Design and Decision Method Analysis for Surface-to-Ground Missiles

In order to obtain better strike effect of warhead for surface-to-ground missiles, AOA (angle-of-attack) should be controlled as close as possible to zero at the end stage of missile flight. This paper will propose two typical structures of AOA convergence autopilots, present design methods respectively, and compare stability as well as rapidity. At the end, conclusion and simulation will be established about how to decide which control method to be used according to different on-board equipment.
