A New Design Approach of Fuzzy Controller for Shunt Active Power Filter

摘要

This article presents a new approach for designing a fuzzy controller for a shunt active power filter without the experience of specialist. Moreover, a new method for calculating reference currents, synchronous detection with Fourier, is also proposed in this article. The hardware in the loop simulation technique is applied to simulate harmonic elimination via a shunt active power filter using the new ideas proposed herein. The eZdsp F28335 (Spectrum Digital Incorporated, Stafford, Texas, USA) cooperates with the Simulink (The MathWorks, Natick, Massachusetts, USA) program for hardware in the loop simulation. The results confirm that the fuzzy controller designed by the new approach can provide a good performance, and it is more robust compared with the proportional and integral controller when the system parameters are changed.
