基于短时网格分形维数的电能质量扰动检测
As far as the nonstationarity during the long period operation of machinery was concerned , the application of adaptive linear element ( adaline ) neural network to prediction of nonstationary time series was studied . the relationship between adaline and auto regressive ( ar ) model was analyzed , and the method to determine the number of input neurons in adaline prediction model according to bic criteria was presented . the effect of the adaptive learning rate on prediction was also analyzed
针对生产实践中设备运行的非平稳性，基于动态预测思想，研究了非平稳时间序列的自适应线性单元( adaline )神经网络预测，讨论了adaline和自回归( ar )模型之间的关系，提出根据ar模型定阶方法确定adaline预测模型的输入神经元数目，分析了自适应学习率对预测性能的影响，为机械设备状态预测提供了一种方法。
