The proposed paper deals with the complete analysis which is basis of common tuning procedure variable sampling Repetitive Controllers for adjustable output frequency applications. described approach can be applied without limitations to grid-tied inverters (narrow variations), as well AC waveform generators (wide variations). operation keep Control main delay line at a constant size, resulting...

This paper introduces a new method for synthesizing multiple-period repetitive controllers. The main innovations in the synthesis procedure presented in this article are two. The first one is that this technique yields a solution compatible with the integration of the computed multiple-period repetitive controller into a minimum-variance adaptive control scheme. The second innovation is that th...
