| 摘 要： | 针对火电厂双进双出钢球磨煤机直吹式制粉系统这一大滞后、强非线性系统,其制粉出力较难直接测量的问题,在Suykens的最小二乘支持向量机稀疏化算法的基础上,提出一种更好的改进方式,即在删除一些过大或过小的训练样本的同时,也将变化率过大的数据删除,避免了坏样本对模型的影响,简化了LS - SVM模型.改进后的最小二乘支持向... |

| Abstract: | According to the problem that the direct-fired system with duplex inlet and outlet ball pulverizer is a large time delay and strongly nonlinear system,its mill output is difficult to be directly measured.In this paper,a better improvement algorithm was proposed based on the Suykens' sparseness method of least squares support vector machines(LS-SVM).This new method is that when deleting some too large or too small training samples,the large variety-rate data were also deleted.This has simplified the LS-SVM m... |
