Abstract

The fault source of the complex hydraulic system is difficult to identify due to the multiplicity

complex creating and strong concealment. A hierarchical analysis method of identifying the fault source based on the small world network is presented

where the system network is divided into multiple-community construction and then the fault source is searched in a specified community. A network topological structure of complex hydraulic system is constructed and its community center nodes are obtained by selecting the network nodes with larger betweenness and degree. And the Wu-Huberman algorithm is improved to partition the system topological structure into multiple-community construction. According to the change of hydraulic parameters in the hydraulic tubes represented by the connection edges between communities

the community containing the fault source node is determined. The community is further extracted from the system network and its reachable matrix is also evaluated. The fault source is finally identified by means of the reachable matrix. The analysis on lifting fault of hydraulic system of steel rolling furnace and the location of the fault source verifies the method is available for identifying the fault source of the complex hydraulic system.
