Comparison of Different Rule Base Matrix in Fuzzy Logic Controller

Abstract

The development of power electronics technology has been widely applied in various fields. Converters have been widely used in renewable energy and several industrial applications. Many control that used to operate the converter, one of these is Fuzzy Logic Controller (FLC). FLC is used because it has advantages such as fast response and good performance. FLC is a rule-based control system, so the basic rules are made to operate this system by input processing. Fuzzy variable 3x3 matrix rule base is less responsive in achieving steady state conditions. Therefore, a 5x5 matrix rule base fuzzy variable is modified, so that it gets smoother response and faster system to achieve steady state. In this paper, the response of the output voltage to changes in the fuzzy variable 3x3 matrix rule base will be compared to the 5x5 matrix rule base.
