Thermal process model identification based on radial basis function neural networks

In order to accurately reflect the dynamic behavior and realize the whole optimal control of the thermal process,a novel modeling method of the RBF-NN(Radial Basis Function Neural Networks) model is proposed to build nonlinear model.This method is based on entropy clustering and competitive learning algorithm,combined with nonlinear autoregressive moving average(NARMA) model to identify the RBF-NN stucture,and the power vector is gotten by the least square algorithm.Two simulation experiments show that the proposed method of the identification based on NARMA model and RBF-NN can accurately describe the non-linearity of the process and has less hidden nodes.
