摘要： The invention relates to a method for securing the operation of a rotating assembly of a turbomachine, comprising a turbine and a rotating machine, wherein the exceeding of a predetermined speed threshold (Ws) is anticipated by repeatedly carrying out a prediction cycle during which the following steps are carried out: measuring (E1 to E5) quantities related to the operation of the turbomachine including an actual rotational speed (W0) of the rotating assembly thereof; estimating (E6, E7), from said quantities, the engine torque (Cm) and resistant torque (Cr) applied to the rotating assembly; developing (E9 to E12) a value (DC') equal to the difference between said two torques; calculating (E13) a predicted rotational speed (W1) of the rotating assembly at a given time horizon on the basis of said representative value (DC') and the actual rotational speed (W0). An action is carried out (E16) on the operation of the turbomachine in order to limit the extent to which the speed of the rotating assembly thereof is exceeded in relation to said threshold (Ws) if the predicted rotational speed (W1) exceeds this threshold (Ws).

摘要： The invention relates to a data processing system (MODFD) for monitoring a complex system, said processing system being configured to receive state data (MSGPB, MSGCAP) and to merge at least some of the state data items into a failure data item (MSGPC), at least one of said state data items being associated with a confidence indicator (NC2), and the failure data item also being associated with a confidence indicator (NC3). The system is characterised in that the merging is performed using a fuzzy logic technique in order to produce the failure data item, taking account of the respective confidence indicators (NC2) of each of the state data items, and to produce the confidence indicator (NC3) associated with the failure data item.
