Objectives

Online detection and localisation of faults in vital control loops as well as in sensors and actuators (bias, drift, precision loss).

Description

The diagnostic system classifies sampled signals into characteristic patterns and then provides fault localisation by means of pattern matching.

Innovation

The classification of signal patterns is based on a robust estimation of the basic statistical parameters of the signals (first two moments) and an analysis of the oscillations. Detection and localisation are performed by means of simple logical rules and approximate reasoning.

Benefits

Automatic detection of malfunctions in sensors and actuators results in:

  • decreased maintenance costs
  • fewer emergency shutdowns
  • reduced load on the operator
  • improved monitoring of critical emission sensors (e.g., CO concentrations)
