On-Line Identification Of A Chemical Process Using A Minicomputer

The application of a minicomputer is investigated for the on-line estimation of the parameters of a two-stage heat-exchanger from the samples of the input and output data with the system under operation. Two methods for on-line identification are considered, and the minicomputer is also used for monitoring all the measurements. The results indicate that not only is it possible to update the estimates during the sampling interval, but there is considerable time available for control purposes as well.
