| Abstract: | The approximation of a fixed-bed reactor model with nonlinear and distributed parameters by using a bilinear state model is presented, and a bilinearization approachbased on parameter estimation technique is given. The coefficient matrices of the bilinear model are determined by means of the estimation algorithm based on block-pulse functions. The results show that the reduced bilinear model developed can approximate the reactor dynamics more accurately than the linear one over a much wider range around the operating state. |
