Annotation: The control strategy of the power supply system with a predictive model is considered. A new discrete-time model of the autonomous inverter and the output LC-filter to predict the output voltage at a varying load is presented. In accordance with the control strategy, the algorithm generates a switching state of the inverter transistor keys, which minimizes the error between the output and the reference voltages. The proposed method shows a good voltage tracking at low harmonic distortion levels for balanced, unbalanced and non-linear loads.
