Active power filter Dc voltage regulation with fuzzy logic controller

This paper deals with the basis of a fuzzy controller suitable to be used for the regulation of systems by judicious choice of rule bases and intervals for each selected fuzzy variable. Also an algorithm describes the main steps for designing a Fuzzy controller has any number of rules. A direct application to the parallel active power filter (APF) capacitor voltage regulation is presented with their simulation in MATLAB. Also an application with 2
^nd
order system is presented in the case of a variable reference to show the effectiveness of this type of regulators.
