在数据驱动的滚动轴承状态辨识模型构建过程中,针对核极限学习机(Kernel Extreme Learning Machine,KELM)算法中高斯核函数的径向宽度参数,σ,选取不当极易造成模型分类精度差的问题,提出一种核排列优选核参数,σ,的滚动轴承状态辨识方法。首先,将测取滚动轴承振动信号经总体局部均值分解(Ensemble Local Mean Decomposition,ELMD)进行分解并计算其能量熵、排列熵来构建高维的特征向量集;然后,初始化核排列(Kernel Target Alignment,KTA)算法参数:最大核排列值,A,i,和核参数,σ,i,,通过判断核矩阵与理想目标矩阵间距离来调节不同的,A,i,和,σ,i,值,来获取两矩阵距离最短时所对应的,A,i,,此时核参数,σ,i,最优。最后,将上述滚动轴承的高维特征向量集作为输入通过KTA-KELM算法的学习,建立基于KTA-KELM的滚动轴承的状态辨识模型。仿真实验结果表明,与KELM、ELM算法相比,KTA-KELM算法将滚动轴承状态辨识的精度由92.5%和90%提高到98.75%,分别提高6.25%和8.75%。
In the process of data-driven rolling bearing state identification model construction,the improper selection of the radial width parameter σ of the Gaussian kernel function in the Kernel Extreme Learning Machine(KELM)algorithm is very easy to cause poor classification accuracy. A method for identifying the state of rolling bearings based on the kernel arrangement preferred kernel parameter σ is proposed. Firstly,the rolling bearing vibration signal is decomposed by Ensemble Local Mean Decomposition(ELMD)and its energy entropy and permutation entropy are calculated to construct a high-dimensional eigenvector set. Then,the Kernel Target Alignment(KTA) parameters of maximum KTA value Ai and the kernel parameter σi are initialized, and the different kernel parameter values are adjusted by judging the distance between the kernel matrix and the ideal target matrix,so as to obtain the minimum corresponding maximum kernel arrangement value when the kernel matrix distance is obtained,and the kernel parameter at this time is optimal. Finally,the high-dimensional feature vector set of the above rolling bearing is used as input to learn the KTA-KELM algorithm, the state recognition model of rolling bearing is built based on KTA-KELM algorithm. The simulation results show that compared with KELM and ELM,the KTA-KELM algorithm improves the accuracy of rolling bearing state recognition from 92.5% and 90% to 98.75%, which is increase 6.25% and 8.75%.
