FAULT DIAGNOSIS APPARATUS AND METHOD FOR ROBUST TO ENVIRONMENTAL CHANGE

摘要

The present invention relates to a breakdown diagnosing device robust to environmental change and a method thereof. According to an embodiment of the present invention, the breakdown diagnosing device robust to environmental change and the method thereof are able to diagnose a diagnosis object robustly against environmental changes by classifying an extended feature vector which extends an acquisition signal of the diagnosis object through a learning machine classifier, after a feature vector of a breakdown frequency component for each breakdown with respect to an inputted learning signal is extended to be learned by the machine learning classifier.
