Design of Intelligent Lighting Controller Based on Fuzzy Control

Aiming at the problems of excessive energy waste and serious light pollution in traditional lighting system, this paper proposes an intelligent lighting control system based on fuzzy logic control algorithm and ZigBee wireless communication technology. The system uses the illuminance sensor to detect the environmental illuminance information in real time, and provides the data source for the fuzzy logic controller. At the same time, the collected data information is uploaded to the monitoring center through ZigBee communication technology. In this paper, the fuzzy controller of intelligent lighting system is designed, and the corresponding fuzzy control rule table and fuzzy control query table are obtained. By querying the fuzzy control table, different PWM duty cycles are output under different illumination errors, so as to control the brightness adjustment of LED lamp. The simulation results show that the algorithm basically achieves the expected effect, and has good control ability.
