A Detection Method for Non-integer Harmonics Measurement Based on Matrix Pencil Algorithm
As Fourier transformation of non-integer harmonics detection exists the shortcomings,such as spectral leakage,low detection accuracy.A sub-space algorithm —Matrix Pencil algorithm is applied to the field.A more satisfied result can be reached.The matrix pencil algorithm and Fourier transform algorithm are implemented through the MATLAB m-file.Then the paper compared the detection accuracy of the two algorithms under the situation of gaussian white noise and when the sampling data is few.The results show that the matrix pencil algorithm has a more superior performance for non-integer harmonics detection.
