Abstract
Parameters of a three phase mixture of sinusoids with harmonic distortion are estimated by first acquiring samples of the signal for no more than a quarter cycle of the signal, a classifier is applied to the samples to obtain noise and signal parameters. Then, initial parameters are estimated to obtain final parameters.
Claims7
