Abstract

Intelligent Control (IC) is a novel stage of automatic control development. Its development brings a new method for electrical drive systems. Fuzzy Logic Control (FLC) in intelligent control is one of the efficient strategies for the system with nonlinear or imprecise model. This paper has applied Fuzzy Logic Expert System (FLES) to the power circuits for state-monitoring and fault-diagnosis. By the analysis of typical power circuits, a kind of universal configuration of fault diagnostic system has been introduced. The paper has established a foundation for further applications of FLES in maintenance of the power circuits.
