Change detection in vibration analysis — A review of problems and solutions

The paper considers the problem of change detection and diagnosis (CDD) in vibration analysis, from the point of view of challenges and solutions. In this framework, Matlab Toolbox VIBROTOOL is presented, implementing functions for change detection and diagnosis in vibration engineering. Compared to other toolboxes in the same domain, Matlab VIBROTOOL Toolbox promotes blind source separation and advanced processing of information from time-frequency analysis, before the change detection and segmentation. Finally, some applications making use of Matlab VIBROTOOL Toolbox are discussed.
