The invention relates to an on-orbit autonomous anomaly detection method for a hierarchical spacecraft control system. The method is widely suitable for satellite-borne autonomous anomaly detection ofhigh, medium and low orbit satellites, airships, space stations, deep space detectors and other spacecrafts, the robustness and robustness of a spacecraft control system can be remarkably improved, and the in-orbit full-life-cycle stable operation capacity of the spacecraft is improved. According to the method, possible abnormal phenomena of a control system are divided into three levels, namelya single-machine hardware information level, a single-machine data software discrimination level and a system level, and different abnormal isolation and processing methods are formulated according tothe level of the detected abnormality. The method is used for components and data of satellite-borne closed-loop control. Control system anomaly detection is interpreted and processed in a hierarchical manner; hierarchical clarity, logic link definition, complex data and signal processing is not used; the on-orbit application effect shows that the method can effectively improve the autonomy and real-time performance of anomaly detection of the control system, further popularization and application can widely improve the robustness and robustness of the spacecraft control system, and the stable operation capacity of the spacecraft in the on-orbit full life cycle is improved.
