Abstract:
为提高加工过程中刀具磨损状态的识别精度,结合改进的变分模态分解算法(modified variational mode decomposition,MVMD)、自适应回溯搜索算法(adaptive backtracking search algorithm,ABSA)及最小二乘支持向量机(least squares-support vector machine,LS-SVM),提出一种刀具磨损快速识别模型.针对传统信号处理方法存在的模态混叠、噪声敏感等问题,采用瞬时频率均值法预先确定最佳分解模态数,引入降噪型变分模态分解算法进行信号分解;为提高优化效率与自适应性,提出一种改进的自适应回溯搜索算...
