We designed a fuzzy controller for ZigBee equipment’s transmission power adaptive adjustment. The controller is based on RSSI (Received Signal Strength Indicator). It can make a dynamic adjustment on the transmitted power according to the fuzzy control rules. The fuzzy control is suitable to solve the problem which is difficult to deal with in building system mathematical model. What’s more, the fuzzy control system has perfect performance in response speed and antijamming capability. It’s convenient to embed in devices. In this paper we use Ti Company’s CC2530 chip as an experiment object. By using the fuzzy controller we keep the transmission power to the minimum. By this way, the energy consumption can be reduced on the premise of ensuring normal communication. The fuzzy controller system has a good steady-state and dynamic performance, and contributes to the ZigBee system’s stability and low power consumption performance.
