1.1 Diagnosis of discrete-event systems

A system is likely to evolve between normal and faulty operating modes. A faulty operating mode is reached when a fault occurs.

• Methodology

  Diagnosis involves comparing instantaneous information from the system with a reference, or model, representing normal and/or faulty operation.

  • This reference is built using a priori knowledge of the system's operation. When this knowledge is sufficient to build a mathematical or analytical model...
