Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals. Dw proposed solution consists in generalizing the first-order cyclostationary class to the more general first-order cyclo-non-stationary class which enfolds speed-varying deterministic signals.

Inria – Vibration-based condition monitoring of rotating machines in nonstationary regime

Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed. We have elaborated this strategy by distinguishing two types of signatures.

The second type includes random periodically-correlated waveforms known as second-order cyclostationary. Business tools and solutions designed for the global marketplace. This service is produced by Kompass. The principal goal of this thesis is to partially fill in this gap on the basis of a theoretical formalization of the subject and a systematic development of new dedicated signal processing tools. But these works remain limited, dispersed and generally not supported by theoretical frameworks.

In the last decades, vibration-based condition monitoring of rotating machine has gained special interest providing an efficient aid for maintenance in the industry.

However, all these techniques rely on the assump-tion of constant— or possibly fluctuating but stationary— operating regime i. Vibration-based condition monitoring of rotating machines in nonstationary regime.

Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.
