Study on a New Approach of Harmonics Suppression Based on Fuzzy Controller

The present situation and problems of harmonic suppression are discussed .Trying to find a new approach. This article presents the design of a new fuzzy logic regulator for a three-phase inverter using the strategy of the inverter flux vector control method. The proposed control scheme can achieve fast transient responses and at the same time have very low total harmonic distortion in output current during steady-state operation. It is very important to introduce fuzzy logic controller into harmonic suppression.
