Research on DC-Side Voltage Control of Active Power Filter

Article Preview

Abstract:

This paper analyzes the control principle of DC-side voltage from the aspect of instantaneous conversation of energy of active power filter, On the basis of these, to deal with the weakness of larger static error and overshoot about PI control method, a combined controller constituted PI controller and fuzzy controller is proposed. This method combines the merits of PI control and fuzzy control, and has some advantage of small overshoot, fast responses and small static errors. The Matlab simu1ation results show that the proposed method is valid and feasible.
