CONTROLADOR FUZZY PROGRAMADO EM PROCESSADOR NIOS II EMBARCADO EM FPGA

Abstract

This paper presents the implementation of anembedded module which aims to control the flow of acentrifuge, in this stage of sugar production, in which themagma must be centrifuged to yield sugar. This module wasembedded in FPGA and its techniques of fuzzy control wereprogrammed in the NIOS II processor. The prototypeimplemented should control the flow of magma bymodulating a control valve with different angles (0°, -45º,45º, -90º, 90º), allowing the maintenance of a charge thatstabilizes its effective current. Some circuits of signalconditioning were developed to perform the operation of theunit and the monitoring of this process. Another contributionis the development of a specific model for fuzzy controllersto be used in another hardware.Index Terms ⎯ FPGA, fuzzy control, NIOS II, template.
