A Fault Prognosis Strategy Based on Time-Delayed Digraph Model and Principal Component Analysis
Because of the interlinking of process equipments in process industry, event information may propagate through the plant and affect a lot of downstream process variables. Specifying the causality and estimating the time delays among process variables are critically important for data-driven fault pr...
