Abstract

The current tracking control is the important part of APF (Active Power Filter) system. Since APF compensation current contain high harmonic components, the traditional Tustin discretization method distort the current in high frequency, which makes the resonant frequency of the PR controller shifted and affects the compensation effect of APF. In this paper, pre-corrected Tustin transformation method is used to improve traditional PR controller which can track sinusoidal signal of specified frequency with no steady-state error and compensate the harmonics of specified frequency selectively.
