Flight control system sensor hybrid redundancy method based on analytic reconstructed signal

The invention discloses a flight control system sensor hybrid redundancy method based on an analytic reconstructed signal, and relates to the technical field of spacecraft control. With the analytic reconstructed signal designed in the hybrid redundancy method, the analytic reconstructed signal only serves as a hot backup signal under regular work condition of a current sensor system, and does not participate in the decision-making strategy of a monitoring voting system; once the voting result of the monitoring voting system is abnormal, the hot backup signal is started for participating voting, the monitoring voting system is used for comparing each sensor measured value with the analytic reconstructed signal, and correct measured value output is given out. Thus, the capacity of processing process faults by purely depending hardware redundancy is improved, and the redundancy level and fault/work level of the sensor system are improved; the hardware maintenance difficulty in later period is also greatly reduced, and the hardware redundancy configuration of the sensor system can also be appropriately reduced if the correctness of the analytic signal can be guaranteed.
