Abstract

This paper describes an implementation of a fuzzy system. For this purpose, a dedicated architecture of a fuzzy logic controller system was elaborated in a FPGA circuit. This system has 3 independent inputs and 2 outputs and is composed of 4 internal blocks: fuzzification, inference, defuzzification and control. The fuzzy inference processes implemented are the techniques of a calculation of a only activated rules and an application of a parallel processing allows for very quick selection of only active rules from the whole rules base. The distribution and shapes of fuzzy sets allow to activate one or two fuzzy rules for one discrete (sharp) value of the input variable. Input and output linguistic variables and corresponding fuzzy sets were defined.
