چکیده مقاله:

In this study, we simulated heat exchanger controller using LQG controller. MATLAB software has been used widely to indentify deviation from experimental data. We used LQG controller witch is a controller that depends on several penalization variables called tuning knobs. Tuning will be performed by using an optimization technique. For the optimization we need to get a real number instead of probability density function (pdf). A function which maps the pdf to a real number has to be used. It can be the expected value approximated as a sample mean. Other advisablem choice is such value, for which the user requirements satisfied are with given probability. Finally, we found out the model accurate enough to use for laboratory scale. Although we have not examine this model for actual state yet. We also believe that good fitting of simulation and experimental curve can be a good reason for using it as industrial design.
