Intelligent Control of Longitudinal Ventilating in Freeway Vehicular Tunnel

The carbon monoxide(CO) concentration and visibility(VI) are the important environment parameters which need to be controlled to ensure the freeway tunnel being safe. It is the ventilating system that ensures these parameters within the safe area. During the tunnel administration the ventilating system is the main equipment of electricity consumption and need to be controlled economically. The freeway tunnel is an inertial plant with lag, and is exposed to a lot of uncertain disturbance. This paper presents an intelligent control method according to the analyses of longitudinal ventilating characteristics in freeway vehicular tunnels based on pattern recognition and optimal control theory. It is fairly robust and adaptive to the changes caused by later rebuilding of the tunnel, and can achieve the purposes of safety and cost saving.
