Abstract:
A nonlinear robust continuum regression(NLRCR)modeling method combing radial basis function(RBF)and robust continuum regression(RCR)is presented to solve the problem that RCR algorithm hard to build the nonlinear system modeling of high predicting precision.Firstly,this approach uses RBF to carry out mapping transformation from nonlinear sample data to high dimension eigen space.Then,RCR algorithm is used for building linear regression modeling in high dimension eigen space.Simulation experiment is performed to show the effectiveness of this method.And it is utilized to develop a soft sensor model for the gasoline dry point in delayed coking,and highly precise prediction results are obtained compared with RCR and RBF-PLS methods.

摘要:
针对RCR算法难以建立高精度的非线性软测量模型的问题,提出了一种径向基函数(radial basis function,RBF)与鲁棒连续回归(robust continuum regression,RCR)相结合的非线性RCR(nonlinear RCR,NLRCR)建模方法。该方法首先应用RBF将非线性样本数据映射到高维特征空间中,然后在高维特征空间中建立RCR线性回归模型。本文通过仿真实验,验证了方法的有效性。并将其应用于延迟焦化汽油干点的软测量建模中,获得了比RCR和RBF-PLS算法更高的预测精度。
