In order to solve the problem of intermittent fault data acquisition and feature extraction,a new method of analog circuit health state recognition based on feature selection verification is proposed.Firstly,the intermittent fault simulation model of analog circuit is established.Secondly,FSV algorithm is used to obtain the fault data eigenvalue of analog circuit.Finally,the extracted features are trained in HSMM model,and a classifier of analog circuit health state based on HSMM is established to realize the recognition of equipment health state.The experimental results show that this method can effectively identify the health status of analog circuits,and open up a new way for the health status identification of analog circuits.
