摘要：In this paper, a dynamic and energy efficient controller based on Fuzzy Rule Based System (FRBS) is designed for controlling the light intensity of streetlights (SLs). As a matter of fact, the climate all across the world along with sunrise and sunset times are not the same, therefore, this paper targets the city of Islamabad, Pakistan as a reference for designing the controller. However, FRBS assisted controller is very flexible to extend and modify the rules to any other city with different weather conditions. It is capable of adjusting the SĽ s intensity level taking into account the month of year, time of day and environmental condition (clear sky, cloudy, foggy and traffic density). The rule surfaces are provided to demonstrate the careful application of fuzzy rules keeping in view even minor environmental variations.
