Title     Data reconciliation of heat exchanger system
Abstract
For the data of flow and temperature collected by the heat exchanger system exists
errors and imperfection inevitably. In order to estimate the variables of the heat exchanger system better, we need to establish the model of heat exchanger system for data’s reconciliation. The purpose of the design is to realize the data reconciliation of heat exchanger system based on Matlab. This design adopts the methods of linear and nolinear to realize the aim. The method of linear involves Lagrange method, nonlinear model’s linearization and projection matrix. The nolinear method adopts fmincon function of Matlab. Finally,we compare the two methods.
Keywords  Heat exchanger system、data reconciliation、fmincon function、
