Controlador FUZZY tipo 2 com programação em verilog das funções de pertinência

Abstract

The fuzzy type-2 fuzzy inference system presents a superior performance in relation to other methods for applications in systems with uncertainty. This work presents the architecture of a SIF type-2 that aims to use the trapezoidal membership function that ensures faster and simpler circuits. The architecture implemented in FPGA consists of five blocks, fuzzifier, inference, rule base, type-reductor and defuzzifier. The hardware presented consists of two 8-bit inputs with three trapezoidal membership functions for each input, nine rules and an 8-bit output with three membership functions. The Verilog implementation results are compared with the same architecture implemented in Matlab® using the Toolbox for type-2 fuzzy.
