This work presents a new feedback control method for nonlinear grid-connected power electronics converters. Specifically, this paper introduces L-infinity robust control, which is an iterative algorithm based on LMIs (Linear Matrix Inequalities). The paper presents the nonlinear differential algebraic equations of the network under study, linearizes it under an operating point and using the linearized model of the converter, a L-infinity feedback control is computed. The performance of the proposed control scheme is validated analytically and through Matlab/Simulations under nominal conditions, disturbances and parameters uncertainties.
