This paper presents the autonomous control for UAV. The autonomous control concept and autonomous control level (ACL) metrics that can measure autonomy of UAVs are introduced. Compared with manned aircraft control task in battlefield, the functions of autonomous UAV system are organized. According to the laws of increasing precision with decreasing intelligent (IPDI), the architecture of autonomous control for UAV is given. The architecture can be divided into three levels: execution level, coordination level and organization level. The constraint conditions and realizations of coordination level and organization level are studied comprehensively. The key hardware and software technologies for multi-tasks are modularized depending on the requirements of mission. The software technologies are distributed to stages of flying particularly.
