基于ls？svm和gm的球磨机料位动态软测量
, PP. 77-81
Keywords: 钢球磨煤机,料位,动态软测量,最小二乘支持向量机,灰色模型
Abstract:
提出了一种基于最小二乘支持向量机(ls-svm)和灰色模型(gm)的钢球磨煤机料位动态软测量方法,分析了料位的影响因素,确定了软测量模型的辅助变量;基于ls-svm建立料位软测量静态模型,将静态模型测量结果与实际值比较,获得测量误差时间序列,并采用gm对其建模和预测;将预测的误差结果与静态模型输出进行叠加,实现对测量结果的动态校正。实际应用结果表明,该方法能够有效地反映料位的变化趋势和动态特性,比单纯ls-svm模型测量具有更高的精度和适用性。
