Abstract :
The aim of this paper is to present a Repetitive Controller which is able to adapt its frequency response according to the frequency of a reference signal. The proposed controller is based on the Multi-Rate feature, and is intended to control the output voltage of an inverter operating in the islanding mode, when the Droop Control Method is implemented. The Variable Multi-Rate Plug-in Repetitive Controller is easy to design, and it allows obtaining a much better output voltage total harmonic distortion than that obtained by means of the conventional Repetitive Controller or the Proportional+Integral controller.
