Abstract:

The recently introduced proportional-resonant (PR) controllers and filters, and their suitability for current/voltage control of grid-connected converters, are described. Using the PR controllers, the converter reference tracking performance can be enhanced, and previously known shortcomings associated with conventional PI controllers can be alleviated. These shortcomings include steady-state errors in single-phase systems and the need for synchronous d–q transformation in three-phase systems. Based on similar control theory, PR filters can also be used for generating the harmonic command reference precisely in an active power filter, especially for single-phase systems, where d–q transformation analysis isn't specifically pertinent. Another favorable position related with the PR controllers and channels is the possibility of executing specific symphonious pay without requiring inordinate computational assets. Given these points of interest and the conviction that PR control will discover boundless applications in grid interfaced converters, PR control hypothesis is changed in detail with various reasonable cases that have been actualized already, portrayed obviously to give a far-reaching reference on PR control and separating.
