针对隧道纵向通风特点,构建了面向通风控制的静态模型,以此静态模型为依据设计了一种纵向通风控制策略。所设计控制器的目的是将隧道内的污染物浓度控制于某个设定的限值之下。该静态模型的特点是显式地将风机功率作为系统输入,将隧道内通风速度简化为风机功率的一次函数,并通过某隧道的实际检测数据验证了这种处理方法的合理性。在此基础上设计的控制策略较为直观,并结合实例给出了简要的控制流程和控制参数整定方法。
Aiming at the characteristics of tunnel longitudinal ventilation, a static model oriented to ventilation control is constructed. Based on the static model, a longitudinal ventilation control strategy is designed. The purpose of the controller is designed to control the concentration of pollutants in the tunnel below a certain set limit. The characteristic of the static model is that the fan power is used as the system input explicitly, the ventilation speed in the tunnel is reduced to a linear function of the fan power, and the actual detection data of a tunnel verifies the rationality of this method. The control strategy designed on this basis is more intuitive, and gives a brief control flow and control parameter setting method.
