Abstract
A method for controlling an electrical converter system is provided herein. The method includes determining a switching signal and a reference trajectory of at least one electrical quantity of the electrical converter system over a horizon of future sampling instants; generating a sequence of averaged switch positions from the switching signal over the horizon; determining a sequence of optimized averaged switch positions with optimized averaged switch positions by optimizing a cost function based on the sequence of averaged switch positions; determining an optimized switching signal for the current sampling interval by moving switching transitions in the switching signal, such that the average of the switching signal with the modified switching transitions equals the optimized averaged switch position; and applying at least the next switching transition of the optimized switching signal for the current sampling interval to the electrical converter system.
