This paper presents a robust optimal nonlinear control scheme for a three-phase inverter, which is connected to the utility grid through an L filter. The control objective is the regulation of the active and reactive power injected to the utility grid. The optimal controller synthesis is based on the optimal control theory, where it is considered the minimization of a performance index (cost functional), which results in an efficient control strategy. Real-time experiments are presented to demonstrated the effectiveness of the proposed control methodology.
