摘　　要：针对天然采光百叶窗智能控制中存在自适应能力差,控制精度不高,采光效果不佳,不能满足舒适性照明需求的问题,采用双模糊控制器来对百叶窗进行自适应调节。通过利用太阳高度角及天空光模式来确定初始百叶窗开度,利用工作面照度与期望照度的差值和差值变化率来对百叶窗开度角进行修正,提高控制精度,满足舒适性照明需求。经过实验测试,双模糊控制器比单模糊控制器控制精度更高,自适应能力强,能够满足舒适照明的目标。Aiming at the problems of poor self-adaptability,control accuracy is not high,poor lighting effect and unsatisfactory lighting requirements for natural daylight shutters intelligent control.The double fuzzy controller is adopted to adjust the louver adaptively.The initial louver opening is determined by utilizing the solar elevation angle and the sky light pattern.The differences between the illuminance of the work surface and the desired illuminance and the rate of change are used to correct the opening angle of the louver.Control accuracy is improved to meet the comfort lighting requirements.After the experimental test,the double fuzzy controller has higher control precision than the single fuzzy controller,adaptive ability is stronger,comfortable lighting of the target can be met.
