公路隧道纵向式通风控制系统研究

Research on the road tunnel longitudinal ventilation control systems

研究和设计了一种基于模糊控制的公路隧道通风控制系统。控制系统的输入量在原有反馈信号——污染物浓度基础上 ,加入了车流量前馈信号 ,由前馈和反馈信号共同合理地完成对通风设备的控制。通过与传统的分级式反馈控制系统对比 ,模拟仿真结果表明 。

This paper researches and designs a road tunnel ventilation control system based on the Fuzzy Logic Control(FLC).To present a better solution,its input parameters contain not only the pollutant concentration,but also the vehicle flow rate as a feedback signal.In term of the computer simulation results,the FLC system is better than the feedback control system at the road tunnel ventilation.
