Abstract
An analog circuit fault mode classification method comprises the following implementation steps: (1) collecting M groups of voltage signal sample vectors Vto each of fault modes Fof the analog circuit by using a data collection board; (2) sequentially extracting fault characteristic vectors Vof the voltage signal sample vectors Vby using subspace projection; (3) standardizing the extracted fault characteristic vectors Vto obtain standardized fault characteristic vectors; (4) constructing a fault mode classifier based on a support vector machine, inputting the standardized fault characteristic vectors, performing learning and training on the classifier, and determining structure parameters of the classifier; and (5) completing determination of fault modes according to fault mode determination rules. The fault mode classifier of the present invention is simple in learning and training and reliable in mode classification accuracy.
