Test Configuration for Incipient Fault Detection

Information sensing and test are premise and foundation of (Equipment Health Management, EHM), a reasonable sensor configuration not only provide accurate and complete fault information, but also improve fault diagnostics, fault prognostics and health state evaluation capability. To address the problem that the traditional test selection and optimization are mainly for fault detection and isolation, then, testability indices for EHM are firstly formulated quantitatively, then, test optimization selection model which minimizes test cost is modeled, and the generic algorithm is introduced to solve the problem. At last, a simulation case and an application case are given to verify & validate the proposed model and method.
