摘　　要：公路隧道通风系统主要用于降低隧道内污染物浓度。射流风机的控制方法是通风系统设计的核心。通过对不同通风控制方法的比较,根据城市隧道的特点,确定采用模糊控制对隧道进行通风控制。并依据CO浓度和烟雾浓度之间具有相互的独立性,提出了建立两个独立的模糊控制器,利用两个模糊控制器分别进行推理运算得到各自的输出。最后比较两个输出,采用最大运行台数控制原则得出射流风机的运行台数。Road tunnel ventilation system is used for reducing the pollutant concentrations inside the tunnel. The control method used is the core of the ventilation system. According to comparing the different ventilation control methods and the characteristics of city tunnel, the fuzzy control to the tunnel jet fans is put forward. Based on the independence between the carbon monoxide（CO） concentration and smoke（VI） concentration, two independent fuzzy controllers are establishment： CO concentration fuzzy controller and smoke concentration fuzzy controller. Then the two fuzzy controllers use fuzzy speculative respectively corresponding operation to get their outputs, according to the outputs to decision the number of jet fans increases or decreases to start or stop.
