The first type includes deterministic waveforms known as first-order cyclostationary. Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.

Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed.

Vibration-based condition monitoring of rotating machines in nonstationary regime. In this case, these techniques fail in analyzing the produced vibration signals. Create your web page Haltools: Dany Abboud 1 AuthorId: 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.

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 monitoring of rotating machine has gained special interest providing an efficient aid for maintenance in the industry. The data we collect are only those necessary for the proper use of our service.

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.
