Abstract

The use of an inverter with an output LC filter allows for generation of sinusoidal voltages with low harmonic distortion. However, the controller design becomes more difficult. This paper presents a new and simple control scheme using predictive control. The controller uses a model of the system to predict, on each sampling interval, the behavior of the output voltage for each possible switching state, then a cost function is used as a criterion for selecting the switching state that will be applied during the next sampling interval.
