Robust control of temperature in hot-air tunnel

This paper is aimed to application of simple continuous-time robust regulators of PI and PID type designed through general solutions of Diophantine equations in the ring of proper and stable rational functions to control of temperature in laboratory model of hot-air tunnel of which mathematical model is supposed to include parametric uncertainty. One of the main advantages of the proposed algebraic approach to control design is the existence of a single positive tuning parameter. The contribution contains both identification and control experiments.
