摘要： 射频识别(RFID)读写器一般以恒定功率工作，会导致电能的不必要消耗。针对该问题，提出一种基于模糊控制理论的RFID读写器功率自适应调节策略，在前后2次读取RFID标签数差值的基础上，采用相应模糊控制算法动态改变RFID读写器的输出功率，从而优化输出。仿真测试结果表明，该策略能明显降低读写器的能耗。

Abstract: Radio Frequency Identification(RFID) reader usually works at the invariant output power, and thus causing the unnecessary consumption of electrical energy. Aiming at this problem, this paper presents a self-adaptive adjusting strategy for RFID reader power based on fuzzy control theory. The strategy adopts corresponding fuzzy control algorithms to adjust dynamically the output power of RFID readers based on difference of RFID tag number timely. Simulation test result shows that the strategy can reduce the consumption of electrical energy.

Key words: Radio Frequency Identification(RFID) reader, middleware, fuzzy control, self-adaptive
