However, all these techniques rely on the assump-tion of constant— or possibly fluctuating but stationary— operating regime i. The second type includes random periodically-correlated waveforms known as second-order cyclostationary. Please fill in your login and password Login.
INSA de Lyon, Dany Abboud 1 AuthorId: The first type includes deterministic waveforms known as first-order cyclostationary.
Three different but complementary visions have been proposed rournante deal with the changes induced by the nonstationarity of the operating speed. Frequent updates ensuring high quality data.

Dany Abboud 1 Details. Business tools and solutions designed for the global marketplace. But these works remain limited, dispersed and generally not supported by theoretical frameworks. 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 fibratoire tools.
Friday, September 23, – 4: Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed. In this work, the nonstationarity of the regime is confined to that of the speed— i. This issue, therefore, has occupied the scientific committee in the last decade and some sophisticated signal processing techniques have been conceived to deal with regime variability.

The 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.

In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools.

In the last decades, vibration-based condition tourbante of rotating machine has gained special interest providing an efficient aid for maintenance in the industry. Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes.

Vibration-based condition monitoring of rotating machines in nonstationary regime. In this case, these techniques fail in analyzing the produced vibration signals.
We have elaborated this strategy by distinguishing two types of signatures.
