Order tracking analysis is often used to find the critical speeds at which structural
resonances are excited by a rotating machine. Typically, order tracking analysis is
performed via non-parametric methods. In this report, however, we demonstrate
some of the advantages of using a parametric method for order tracking analysis.
Specifically, we show that we get a much better time and frequency resolution,
obtain a much more robust and accurate estimate of the RPM profile, and are able
to perform accurate order tracking analysis even without the tachometer signal.
