Title
Evolvable Building Blocks for Analog Fuzzy Logic Controllers
Abstract
This work discusses the use of an Evolvable Hardware(EHW) platform in the synthesis of analog electroniccircuits for Fuzzy Logic Controllers. A Fuzzy LogicController (FLC) is defined by a collection of fuzzy if-thenrules and a set of membership functions characterizingthe linguistic terms associated with the inputs and outputof the FLC. The EHW analog platform, named PAMA-NG(Programmable Analog Multiplexer Array - NextGeneration), is a reconfigurable platform that consists ofintegrated circuits whose internal connections can beprogrammed by Evolutionary Computation techniques,such as Genetic Algorithms, to synthesize circuits. ThePAMA-NG is classified as a Field Programmable AnalogArray (FPAA). FPAAs have appeared recently andconstitute the state of the art in the technology ofreconfigurable platforms. These devices will become thebuilding blocks of a forthcoming class of hardware, withthe important features of self-adaptation and selfrepairing,through automatic reconfiguration. This article of these devices enables the self-adapting and selfrepairingfeatures, which are important in applications where circuits need to operate for long periods in harshenvironments. This is especially appealing to FLChardware that could be used in this type of applications.Previous FLC analog hardware implementations [7][8]are based on designer's experience and intuition followingelectronic circuit design common rules. On the other hand,synthesis of unconventional electronic circuits isparticular appealing to EHW [6]. Its use in the synthesisof analog electronic circuits that implement fuzzyinference systems has been explored recently withpromising results [9][10][11].This paper is divided into four additional sections. Thesecond presents some basics architectural aspects of FLCsand their analog hardware implementations. Sectiondescribes the PAMA (Programmable Analog MultiplexerArray) [12] and the modifications carried out to evolvefuzzy circuits with the new platform PAMA-NG (PAMA- Next Generation). Section 4 presents case studies thatfocus on the evolution of building blocks for analog FLCs.Section 5 concludes the work.
