Research Abstract

In this study, feature extraction from a transient response of a semiconductor gas sensor is investigated. For the sensor response given as the step response of the first-order lag system, the sensor output can be approximated as a sum of exponentials by Prony's method. We have shown that the method can be interpreted by the subspace based identification method. The model parameters can be estimated as the time constant and the gain, which are strongly related to characteristics of gases. The parameters can be used to construct the feature vector for the discrimination of gases. Using the estimates as features, it has shown that the discrimination of gases can be improved.
