In this paper, an output-based disturbance rejection control strategy is designed for the single-phase DC-AC inverter system. By means of the lumped disturbance estimation as well as virtual state estimations, an output feedback control combined with an additional feedforward compensation is proposed. It is shown that under the proposed control method, the asymptotically output voltage tracking performance is obtained even in the presence of various disturbances/uncertainties. Stability analysis for the closed-loop system is demonstrated by using the Lyapunov stability method. Simulation results show the feasibility and effectiveness of the proposed method.
