A fundamental component extraction and its frequency estimation of the input signal were realized in this paper based on adaptive notch filter technique.To compensate for its weakness in harmonic attenuation,an infinite impluse response pre-filter was designed.The fundamental reference signal could be exactly extracted even under distorted input signals and its frequency could be adaptively estimated.Finally,the effectiveness of the presented scheme was validated via experimental researches based on dSPACE rapid control prototyping system.
