Abstract
The shunt active filter, which is connected to power systems in parallel with the load, is considered as a current source. However, the shunt active filter is actually realized by current control using the voltage source type inverter. Authors applied multirate perfect tracking control (PTC) to current control for the shunt active filter. Although conventional single-rate deadbeat control could not guarantee zero tracking error for arbitrary reference signals, the proposed multirate control can achieve perfect tracking at every sampling point. In this paper, we propose a novel method to generate repetitive compensation signals. Simulations and experiments are shown to verify the effectiveness of the proposed method.
