Advance in Modern Analog Circuit Intelligent Fault Diagnosis Methods
Yi Zhu · Electronic Design Engineering · 2012
The reliability and economy requirements of electronic system are getting higher and higher,which make analog circuit fault diagnosis become more and more important.Based on the introduction of the cause and classification for analog circuit faults,the characteristics of analog circuit faults were analyzed in detail.According to the deficiency of traditional methods,modern diagnosis methods based on artificial intelligence and modern information processing were introduced,including expert system diagnosis methods,neural networks diagnosis methods,fuzzy fault diagnosis methods and kernel-based methods.The principle,advantages and disadvantages,research advance and representative application of each method are introduced systematically at the same time.The issues which modern diagnosis methods are confronted and the future research directions are discussed at last.
