Automatic synthesis of analog fuzzy controllers

Abstract

In this paper, a silicon compiler for analog fuzzy controllers is presented. The layout is automatically generated automatically, startingfrom a set of user specificationssuch as numberof rules, number of inputs and maximum current (power consumption). This tool relies on a library of parametrizable basic cells designed in a CMOS 0.7 m technology.The structure of the defuzzificationpart of the controller is based on the modular definiton made in [1]. This structure allows multi–input, multi–output fuzzy logic based controllers. It also a allows an easy extension of the controller (Serial or parallel conection of them to obtain controllers with more inputs or rules).
