Research on Fuzzy PI Compensating Current Control of Three Level Active Power Filter

Abstract:

This paper presents a new method which combines the fuzzy theory with the traditional PI control to obtain the accurate tracking of the compensating current of the active power filter (APF) in full frequency range. Online adjustment of the parameters of the controller is realized by using fuzzy reasoning and defuzzication, so as to achieve the accurate tracking of the compensating current and thereby improve the capabilities of the APF to suppress the harmonics effectively. Simulation analysis and experiment results verify the effectiveness of the presented method.
