Kernel selection for sensorless speed measurement of AC machines (Wigner vs Page representation)
This paper presents the analysis of the kernel effect on time-frequency representations used in measuring AC machine rotor speed, without the use of shaft mounted sensors. This speed measuring method is based on the analysis of speed related harmonics that arise from rotor slotting. In the present work, the use of the Wigner-Ville distribution and the Page distribution are analyzed.
