“…Structural model decomposition methods can be used to systematically compute the submodels. The use of local submodels leads to increased scalability of the diagnosis algorithm Thompson, 1994) and increased diagnosability. They have been successfully used for fault diagnosis in industrial (Arogeti, Wang, Low, & Yu, 2012) and aerospace applications (Fravolini & Campa, 2009).…”

a b s t r a c tQuick, robust fault diagnosis is critical to ensuring safe operation of complex engineering systems. A fault detection, isolation, and identification framework is developed for three separate diagnosis algorithms: the first using global model; the second using minimal submodels, which allows the approach to scale easily; and the third using both the global model and minimal submodels, combining the strengths of the first two. The diagnosis framework is applied to the Advanced Diagnostics and Prognostics Testbed that functionally represents spacecraft electrical power distribution systems. The practical implementation of these algorithms is described, and their diagnosis performance using real data is compared.
