Research-AR-on-vibration-signals
本算法程序基于实测汽轮机振动信号进行了测试及性能分析。理论分析及仿真结果表明,AR模型谱估计算法在阶次合适的情况下,能够取得较好的方差及分辨力性能,适合于振动信号的功率谱估计,且AIC准则为确定合理的模型阶次提供了有效依据。(This algorithm based on the measured turbine vibration signal testing and performance analysis. Theoretical analysis and simulation results show that, AR model spectrum estimation algorithm in appropriate circumstances the order, the variance can achieve better performance and resolution, suitable for vibration signal power spectrum estimation, and the AIC criterion to determine a reasonable model order provides an effective basis.)

HHT
把HHT和神经网络结合起来,识别出是否故障。对于HHT变换,这里用到的是它的IMF分解,然后用能量理论来判别哪些模组是虚假分量,哪些是是真实分量。对于EMD分解后的谱进行特征提取 ,利用的理论基础就是模糊熵。计算出真实 分量的模糊熵,作为输入层;输出层为两个神经元,为0(故障 )1(正常 (正常 )判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)
