IDENTIFICATION AND CONTROL OF THERMAL PROCESS WITH SIMULINK DESKTOP REAL-TIME AND NI PCIe-6321

Abstract

Identification and control of thermal process is a very common problem in
process control. In fact, the thermal model is identified based on input/output
data obtained from the experimental process because some of the parameters
related to the process are difficult to determine exactly like the heat transfer
coefficient. Normally, when identifying a model based on transient response, the
first order plus dead time is used to describe the thermal object. In this paper, we
will use both first order plus dead time and second order model to identify
“CE103-Thermal Process Control” model of TecQuipment based on the step
responses obtained by using PCIe-6321 card of NI (National Instruments) and
select the suitable model to control the thermal process in real-time based on PC
with “Simulink desktop real-time” toolbox of Matlab/Simulink. The identification
and control results have demonstrated the performance of the obtained model.
