摘　　要：针对隧道照明存在大量电能浪费的现象,在分析现有隧道照明控制方式的基础上,提出基于模糊控制的隧道照明无级调光控制系统,阐述系统控制结构及模糊控制器的设计。以洞外亮度和交通量作为系统的输入,采用白光LED作为光源,实现自适应控制,不仅可以实现连续调光,而且节约能源。通过仿真实验,分析比较在不同亮度和交通流量下洞内照明变化曲线,验证了该方法的有效性。Aiming at the problem that tunnel lighting wastes a lot of electric energy,after analyzing the current control model of lighting in tunnel.The control constructure of the system and the design of the fuzzy controller are described.In this system,the traffic flow and illuminance out of the tunnel are input,and the LED is used as lighting source.During the process,the adaptive control is realized,and continuous adjustment of tunnel illuminace is achieved,which shows that this system saves energy.The illuminance curve in the tunnel is compared through simulation with those of different illuminance out of the tunnel and different amount of trofic.The result shows that the method is effective.
