Implementation of Single Input Fuzzy Logic Controller for Boost DC to DC Power Converter

摘要

This paper describes the application of the Single Input Fuzzy Logic Controllers (SIFLC) to regulate the output voltage of a Boost (step-up) DC to DC power converter. The SIFLC is derived from the Signed Distance Method which reduces the multi-input Fuzzy Logic Controller (FLC) with Toeplitz rule table structure to a single input FLC. Effectively, it allows for the rule table to be approximated to a one dimensional piecewise liner control surface. To validate the effectiveness of the SIFLC compared to the Conventional FLC, MATLAB is simulation carried out. Controller is implemented in digital using FPGA and experimental results are exhibited.
