Nowadays, there is an increasing interest in using FPGA devices to design digital controller, and a growing interest in control systems based on fuzzy logic where the Defuzzification stage is of primordial importance. In this work we are presenting the design, modeling and simulation of a fixed point defuzzification VHDL method. The modeling and simulation of this stage is realized in Simulink through the Xilinx System Generator, and a second inference system was implemented with Matlab code. Comparative analysis of both systems and result are shown.
