摘　　要：从分形维数概念出发,提出了基于短时分形维数的模糊控制滤波方法.提出了网络分形维数和短时分形维数的新算法,讨论了模糊控制滤波方法中的模糊控制参数的选取.通过在虚拟仪器(VI)LabVIEW 6.i平台上对数字印制电路板电流传导干扰信号进行实时检测,结果表明:经过信号处理,该系统具有信噪分离、测量电流传导干扰信号的功率谱等功能.According to the concept of fractal dimension, the author puts forward a method of fuzzy control filter based on short-time fractal dimension. That method brings up new algorithm of network fractal dimensions and short time fractal dimensions, and fuzzy control parameter is discussed. In virtual instrument（VI） Lab VIEW 6. i software workbench,real-time detection of the current conduction interference signal in digital PCB is realized. By signal processing, the system has the following measurement functions ：signal-noise spearation, power spectrum of current conduction interference signal, etc. Result shows that the method is feasible and effective.
