一种室内采光模糊控制器的研究

Study on a Kind of Fuzzy Controller for Indoor Lighting

针对室内采光要求,对于室内含有百叶遮阳帘和照明补光的系统,本文提出了一种基于二维纯模糊控制算法的计算机室内采光控制系统。介绍了该系统的控制原理、模糊变量、隶属度函数以及控制规则表的确定,也给出了控制算法的程序模块。该系统采用查询模糊规则表的方式,通过硬件接口电路有效地控制遮阳百叶的遮阳角度,并在特定条件下进行室内照明的智能补光控制。在满足视觉舒适度的同时节约了室内照明用电。

To meet the requirement for lighting indoors, this paper proposes an indoor lighting control system based on computerized 2-dimensional purely fuzzy controlling algorithmic approach used for the indoor shutter curtain ＆ light compensating system. And meanwhile, the control principle, fuzzy variables, membership functions are presented, control rules table is determined and program module of controlling algorithmic approach is given as well. By means of fuzzy control rules table, the system can control effectively the shading angle of shutter curtain by hardware interface circuit and can, under a particular condition, also smartly control light compensation for indoor light, resulting in both electricity conservation for indoor lighl and good visual comfort.
