摘要

本文提出了一种基于模糊控制的2.4GHz无线通信自适应阻抗匹配方案。为此,采用由零阶Takagi-Sugeno-Kang模糊控制器控制的双端口无源匹配网络,使系统迭代直至达到匹配点。给出了将模糊控制器与π、T和L阻抗匹配网络耦合的几个实验。本文讨论了用MATLAB 7.1对所述算法进行仿真的初步结果,并与最小均方阻抗匹配方法进行了比较。

An adaptive impedance matching approach based on fuzzy control
In this work an adaptive impedance matching scheme for 2.4GHz wireless communication, based on fuzzy control, is proposed. For that purpose, a two-port passive matching network controlled by a zero-order Takagi-Sugeno-Kang fuzzy controller is used, allowing the system to iterate until the matching point is reached. Several experiments using the fuzzy controller coupled to π, T, and L impedance matching networks are presented. Preliminary results derived from MATLAB 7.1 simulations of the described algorithm, and a comparison with a least mean square (LMS) impedance matching approach, are discussed.
