Design of Fuzzy-PI Control System for Voltage Regulation of Boost Converter

Abstract

One of important component in a voltage regulation system of electric vehicle is a boost converter. In its application, the boost converter often faces several challenges in maintaining performance especially under the influence of varying load conditions. In order to make the boost converter function under various conditions, an efficient and adaptive control with optimal performance needs to be realized. This paper proposes the Fuzzy-PI method for voltage regulation in the boost converter. The application of this method is expected to improve the performance of the boost converter. Based on the test results, Fuzzy-PI control can provide the best superior performance when contrasted with other conventional methods with the characteristics of quick rise time, low overshoot, and minimum steady state error. The system also possesses high disturbance robustness and rapid adaptation to change, hence a good and effective solution for voltage regulation in various applications.
