基于混合型鲁棒输入训练神经网络的非线性数据校正方法及其应用
Nonlinear data correction method and its application based on hybrid robust input-training neural network
摘要
Abstract
A nonlinear data correction model, hybrid robust modified input-training neural network model, is presented by integrating process mechanism constraint equations into the neutral network model. In the network structure of proposed model, constraint equations are included in the objective function of network training by penalty function method. The network learning method is derived based on BP(back propagation) algorithm, and the algorithm steps are also given in this paper. The case study is conducted to detect and validate some data sets measured from and 1# high pressure heater in a 1 000 MW unit and a five-dimension nonlinear system, and the result indicates the validity and robustness of the proposed model, which can ensure the accuracy and reliability of data correction in case of multi-point fault under system mechanism constraints.关键词
