As human being go further in space and the space exploration become more complex, higher reliability of spacecraft is required. Thus, the fault-tolerant control technology of spacecraft has received extensive attention. The article studies the current status of fault-tolerant control technology of spacecraft attitude system, and summarizes the recent achievements in fault-tolerant control of spacecraft attitude at home and abroad. Furthermore, the article pays much attention to the progress of fault-tolerant control technology based on the theories of adaptive control, sliding mode control, fuzzy control, neural network control, etc., and the advantages and disadvantages of each technical approach are analyzed. Finally, the article looks forward to the future development of fault-tolerant control technology of spacecraft attitude.
