摘要: In this paper we describe a control method for longitudinal ventilation of road tunnels. The proposed consists two main elements: (a) prediction number jet-fans and (b) fuzzy pollutant levels. Based on measurements traffic intensity weather conditions by knowing tunnel parameters, production carbon monoxide, nitrite oxides small particles (soot) is predicted. Estimated values pollutants are then used calculation fresh air volume demand, i.e. required flow determined. One-dimensional force equation estimation that would produce thrust sufficient to provide calculated flow. the same time controller compares measured admissible levels adjusts predicted in order keep within predefined boundaries. tested simulation obtained results compared with currently system Ucka. Finally, field results, implementation method, also presented at end paper.
