Abstract EN
The spectral leakage has a harmful effect on the accuracy of harmonic analysis for asynchronous sampling.
This paper proposed a time quasi-synchronous sampling algorithm which is based on radial basis function (RBF) interpolation.
Firstly, a fundamental period is evaluated by a zero-crossing technique with fourth-order Newton’s interpolation, and then, the sampling sequence is reproduced by the RBF interpolation.
Finally, the harmonic parameters can be calculated by FFT on the synchronization of sampling data.
Simulation results showed that the proposed algorithm has high accuracy in measuring distorted and noisy signals.
Compared to the local approximation schemes as linear, quadric, and fourth-order Newton interpolations, the RBF is a global approximation method which can acquire more accurate results while the time-consuming is about the same as Newton’s.
