Abstract: The research progress on spacecraft fault diagnosis and fault-tolerant control techniques are reviewed in detail. The progress on the spacecraft fault diagnosis techniques are expounded from the model-based methods, the data-based methods, and the knowledge-based methods, respectively. Moreover, the current research status of the fault-tolerant control techniques is also summarized. In addition, some research projects are introduced. Finally, some possible future directions are discussed.
