Improved computing order tracking method and its applications

To overcome the computation singularity problem that the traditional computing order tracking( COT)method is not able to estimate the re-sampling time when a rotor system rotates with an invariable frequency or slowvariable frequency,an improved COT method was proposed based on the cubic spline interpolation. Since the cumulated rotation angle increased monotonically with time passing,the time variable was expressed as a function of the cumulated rotation angle based on the principle that the inverse function of a monotonic function inevitably exists. The cubic spline interpolation method was used to solve the equations and the re-sampling times of equal angles were estimeted under arbitrary rotation condition. Simulated signals and test ones were used to validate the effectiveness of the improved COT method under various rotation conditions. The results showed that the improved COT method can be used to solve the computation singularity probem of the traditional COT method at a constant rotating speed or a slowly-varying one,and it extends the application range of the COT method,so it is more valuabe in engineering applications.
