Regulace protiproudého výměníku. Vytvoření modelu v MATLABu.

Abstract

My bachelor work is aimed to realization mathematical model of counter-flow heat exchanger and its control. It describes, creation of mathematical model, ways of its identification in Matlab, and using surface method's algorithm for identification linear time invariant system. Model is identified as linear time invariant system with lumped parameters, as transfer function in Laplace transform. To this identified system are designed two types of PI controllers. In the end control-loop with these controllers on the math model is checked and also quality of control on the approximated model is evaluated.
