针对PID控制算法存在的一些不足,本文将模糊算法和PID算法相结合,对照明系统对环境的照度进行自动控制,用以调节目标区域的工作面上照度稳定阈值。以照明系统输出电压为输入,人为创建语言控制规则,并依据其进行模糊推理,构成模糊规则表并计算模糊关系,最终获得模糊输出判决。控制光源光照度的变化,实现对照明环境的自动衡光控制,以达到节能与绿色照明。
Aiming at some deficiencies of PID control algorithm, this paper combines fuzzy algorithm and PID algorithm to automatically control the illuminance of the environment for the lighting system to adjust the steady illumination threshold of the working face in the target area. Taking the output voltage of the lighting system as the input, a language control rule is created artificially and the fuzzy inference is made according to the rules. The fuzzy rule table is formed and the fuzzy relation is calculated, finally the fuzzy output decision is obtained. Control light source illumination changes, to achieve automatic balancing of the lighting environment control, in order to achieve energy-saving and green lighting.
