Title: On the identification and robust control of a delayed heat-exchanger process.
Abstract: This contribution presents possible techniques to identify and control a simple heat-exchanger process with delays. An air-liquid heat exchanger is included in the system. Two approaches to determining a model are given to the reader. Namely, an analytic-numerical anisochronic modeling principle and a relay-feedback identification test. Although the delay-free dynamics of the process is very simple, the inclusion of internal delays makes the full dynamics much more complex and tricky, since an infinite-dimensional model is eventually obtained. Such systems are challenging to be controlled. Hence, an algebraic robust controller design is proposed herein, and its performance is verified by simulations and laboratory measurements.
