Fault diagnosis of power electronic circuits based on rough set theory
Tu Juan · Journal of Fujian College of Architecture & C.e · 2004
Based on rough set theory, a new fault diagnosis method of power electronic circuits was presented. Rough set theory was briefly introduced, and the diagnosis process of this method was elaborated. Taking three phase silicon controlled rectifier (SCR) for example, the fault information data was dealt with by means of rough sets. After unnecessary or fault signs were discarded, the correct rule of diagnosis was formed for fault classification. Simulation indicated that this method was of better reliability and simplicity.
