cross-correlation

一种空间电压矢量控制电动机的例子，有点复杂，适合研究比较深奥的matlab仿真(Example of a space voltage vector to control the motor, a bit complicated, appropriate to study more esoteric matlab simulation)

故障信号的采样值，采样频率为100KHZ(Fault signal samples, the sampling frequency is 100KHZ)

核查的关键在于对核材料属性准确、有效地识别[1][2]。利用252Cf作为随机脉冲中子源，对其入射核材料所产生的诱发裂变中子脉冲信号进行采集、处理和分析，得到自相关、互相关、自/互功率谱、功率谱密度比等一系列参数，从而反演核材料内部的反应性的情况，便可用于分析和识别核材料，其基本原理就是252Cf中子源驱动噪声分析测量法[(The result shows that the trained Elman neural network is able to identify the characteristics of correlation function, to distinguish different concentrations, and the average recognition rate reaches 90 , with high robustness.)
