Application of the Elman Network and Synthetically Relational Analysis to Fault Diagnosis for Suction Fan

The theory of Elman network and gray relational analysis was introduced; a method based on the synthetically relational analysis was presented and applied to fault diagnosis of Suction Fan. The same testing fault mode was diagnosed by both the method of Elman network and the synthetically relational analysis respectively. The result shows that the fault diagnosis based on the synthetically relational analysis is feasible and simple.
