【摘要】 变频器高次谐波产生的奇异性信号使交流调速系统不能正常工作,采用小波包分析对奇异性信号进行识别和提取,对系统进行抗干扰处理,有效地抑制了高次谐波对交流调速系统的干扰。更多还原

【Abstract】 High order harmonic of inverter produces singularity signal,make speed governor system can’t normally operate. Wavelet packet theory was applied to extract and identify for the signal,and system was processed for anti-interference ,some interference of high order harmonic for speed governing system were availably eliminated.更多还原
