Abstract: This paper analyzes and summarizes the research status of autonomous observation technology, autonomous decision making technology and control technology involved in intelligent autonomous control systems, and also analyzes the current technical problems of spacecraft control systems in dealing with uncertain environments. Considering the needs of future space missions, a new closed loop structure of “Observation evolution decision action” (OEDA) is proposed for spacecraft, and the characteristics and functions are discussed. The theories and methods involved in observation, evolution, decision making and control action in the OEDA control framework are further given. Finally, the key scientific problems that need to be solved in the practical applications and further development of the control framework are analyzed. 

Key words: Spacecraft, Uncertain environment, Observation evolution decision action, Autonomous control system, Intelligent contral
