摘要

为解决传统的自适应模糊控制器算法过于复杂难以用模拟电路实现的问题

本文研究了输入输出论域可随输入变量的变化而自适应变化的在线自适应模糊控制器及其在非线性系统控制中的应用

并制作了CMOS模拟电路芯片.提出了一种新的尖三角形隶属度函数实现输入变论域的功能

输出变论域部分采用对输入变量进行加权积分并求其绝对值的方法.控制器的其他部分为求小电路和重心法去模糊电路.以上各电路均为CMOS模拟电路

它们和集成的整体电路均在无锡上华(CSMC) 0.6μm工艺下流片

测试结果表明该芯片完成了变论域模糊控制器的功能.

Abstract

The conventional adaptive fuzzy logic controllers are usually too complex for analog circuit implementation.To solve this problem

an on-line adaptive fuzzy logic controller and its application in the control of nonlinear system are studied

whose universe can adaptively change along with the changing of the input variables.Its CMOS analog chip is designed and fabricated.A novel peaky-triangle membership function is proposed to realize the input variable universe part.For the output part of VFLC

the absolute value of the integral of the input variable is used.The other parts are current-mode minimization circuit and a COG (center of gravity) defuzzification circuit.All the above circuits and a whole system were implemented under 0.6μm CMOS standard technology.Their test results show that they fulfill the function of the variable-universe fuzzy logic controller.
