Control of Airflow Speed in Laboratory Model of Hot-air Tunnel

The main purpose of this contribution is to present an approach for controlling the airflow speed in laboratory plant of hot-air tunnel which is modelled as a system with parametric uncertainty. The 1DOF and 2DOF controller design is based on algebraic technique and closed-loop robust stability is analyzed via combination of the value set concept and the zero exclusion condition. Practical applicability of the method is demonstrated through real control experiments.
