【Abstract】 This paper presents a detection approach based on wavelet network for fault of parameter jump. Generally,there are two kinds of fault detection approaches. One is based on signal processing. The other is based on the mathematical model of process,the approach presented here is a combination of the two approaches. It has both the advantages of signal processing and mathematical model,and has increased the precision of fault detection.更多还原
