Design of Louver Shading System for Glass Dome Based on Fuzzy Control

In order to provide a more comfortable reading, a louver shading system based on fuzzy control is designed to regulate the illuminance in the reading area under the dome, which varies greatly with time. A fuzzy controller is designed with the illuminance deviation of the reading area and its rate of change as input and the rotation angle of louver blades as output based on the fuzzy control theory, and the upper computer control system is constructed with LabView. The test operation results show that the designed fuzzy controller effectively regulates the illuminance of the reading area and meets the reading comfort requirements, the reading area illuminance is in the range of500-1,000 lx throughout the day,.The illumination in this range is neither bright nor dark, and reading comfort is strong.
