Combining the Daylight and Artificial Light Based on Fuzzy Logic

The paper present a strategy of artificial lighting control to respond the natural state of daylight based on fuzzy logic control. After building the fuzzy logic controller, the simulations using Matlab program in two scenarios are built. For each scenario, the output responses were surveyed with the whole range of daylight corresponding to each of input statement. The simulation results show that the output of the fuzzy controller is good responsive the equilibrium when the input illumination changes, while the 4 zones scenario have more sensitive result than the 3 zones scenario.
