| 摘 要： | 由于从电机的频谱无法区别出故障电机,因而使用CZT变换(线性调频Z变换)分析采集到的电机数据,判断出电机是否有故障,对电机进行了分类;把采集到的数据分类后训练最小二乘向量机,再把相同维数的数据送入训练好的最小二乘向量机进行判断,最终得出用最小二乘向量机进行电机的故障诊断的准确性,从而说明了用最小二乘向量机进行故障诊断的可行性和可靠性。

| Abstract: | Because the failure of motor can not be distinguished from the spectrum,the analysis of CZT-transform into motor data is started with,it can figure out whether the motor is at fault or not.The motor has been classified.This article describes the classification training after collected data least squares vector machines,then the dimension data into the same training good judgment of least squares vector machines.Finally,this article points out the feasibility and realiability of this diagnosis by using the LS-SVM. |
