The failure signature that has been determined the range for fault diagnosis

摘要

It is a method and apparatus for diagnosing faults. Failure is detected. To determine the one or more process variables that contributed to the failure. I to determine the relative contributions of each of the one or more process variables. Which of the failure signature is as to whether to conform to the failure, it is determined. When the contributions within the relative matching fault signature, the relative contributions of the one or more process variables, occur fit. Each fault signature is associated with fault classes at least one.
