Abstract: A design method of flight controller suitable for various types of air-to-ground missiles is proposed to avoid the redundancy design of flight controller caused by the development of serialized air-to-ground missiles. The differences between the traditional flight controller and the flight controller suitable for serialized air-to-ground missiles are analyzed. Through the determination of multi-loop universal current-limiting resistance，the flight controller can effectively perform various types of missile ignition functions. The type of missile is judged by circuit code recognition，and then the corresponding missile control model is selected to achieve the efficient damage to the threatening target. The proposed method was verified through the closed-loop flight test of a serialized air-to-ground missile. The test data demonstrates that the proposed method can improve the universality of the flight controller，thus improving thedevelopmental efficiency of the serialized air-to-ground missile and reducing the developmental cost.
