DATA-DRIVEN METHODS FOR FAULT LOCALIZATION IN P...

Control systems at production plants consist of a large number of process variables. When
detecting abnormal behavior  these variables generate an alarm. Due to the interconnection of
the plant's devices the fault can lead to an alarm flood. This again hides the original
location of the causing device. In this work several data-driven approaches for root cause
localization are proposed  compared and combined. All methods analyze disturbed process data
for backtracking the propagation path.
