Design of adaptive fuzzy controller for Bolu Highway tunnel ventilation system

The purpose of tunnel ventilation control is to provide a safe and comfortable environment for the users. The tunnel ventilation is optimized by controlling jet fans and dust collectors installed inside the tunnel. The jet fans blow polluted air from inside the tunnel toward air exit ports. The dust collectors remove soot and smoke so that pollutant concentration inside the tunnel is measured by CO ( carbon monoxide) meters. Since this is a process involving many elements which are difficult to quantify exactly, in this paper predictive fuzzy control was introduced to solve this problem. By introducing predictive fuzzy control it was made possible to greatly reduce electric power consumption while keeping the degree of pollution within the allowable limit.
