Automatic tracking control technology is the key design technology of air defense fire control system,also the key technology of the future unmanned weapon equipment development. The paper advances two automatic tracking control strategy,respectively: regeneration tracking controller and tracking differentiator. The design idea of these two controller is from compound control theory,the paper also introduces the basic principle of compound control,regeneration tracking,tracking differentiator. The paper studies and compares two automatic tracking control strategy through computing method,and gives simulation analysis under Matlab/Simulink,provides reference for the engineering design.
