The study on diagnosis strategy design method based on simulation

In order to achieve effective diagnosis strategy, support the fault diagnosis design for PHM (Prognostics & Health Management), a design method of diagnosis strategy based on simulation is presented with a case of certain avionics system. A complete diagnosis strategy can be formed by combing the results of testability simulation and EDA (Electronic Design Automation) simulation, applying the dependency matrix theory and signal acquisition & processing theory. The presented method provides an effective approach to applying optimal diagnosis strategy obtained by simulation to practical engineering design. It can guide actual diagnosis design for PHM, and will be significant to improve the level of diagnosis and testability design of PHM.
