A model of the refinishing spray booth as a plant of automatic control

The authors present a spray booth dynamic model and a short analysis of technological factors, which may influence the dynamics of the controlled parameters. The main idea is to find robust control algorithms (mainly for temperature control), which make the process stable in any operating point. The paper presents a preliminary concept of the temperature and pressure control system dedicated for spray booths. A selected set of results of the temperature stabilization is given in the paper.
