摘　　要：基于自适应陷波器技术实现输入信号的基波分量提取和频率估计,并鉴于其谐波抑制能力不足的问题,设计前置无限冲激响应滤波器,实现在输入信号畸变的情况下基波参考信号的准确提取及基波频率的自适应估计。最后,通过dSPACE快速控制原型系统验证了该方案的有效性。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 re- sponse pre-filter was designed. The fundamental reference signal could be exactly extracted even under distorted input sig nals 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.
