Abstract

This paper proposes a digital Robust Model Reference Adaptive Control (RMRAC) applied to control the output current (by the grid side) of a three-phase LCL-filter to applications in static converters connected to electric grid. The proposed controller is based on a modified RLS algorithm applied to adaptation of the controller gains. Experimental results show the good performance of the proposed control system.
