Fuzzy control for the illumination and temperature comfort in a test chamber

The paper deals with the controlled dynamic thermal and illumination response of human-built environment in real-time conditions. The aim is to harmonize the thermal and optical behavior of a building with regulated energy flows through the envelope. A control system with fuzzy elements for changeable transparent elements of the building envelope was developed. For this purpose a test chamber with an opening on the south aside was built. Energy flows through the envelope are controlled with changeable geometry of the window, realized with the external roller blind, which is automatically positioned. The fuzzy controller for the corresponding positioning of the roller blind in a given combination of outside conditions as external disturbances is the subject of this paper.
