Abstract: A method for controlling an electrical converter comprises the acts of determining an error value based on a difference between an estimated output value and a reference output value, the estimated output value being based on measurements in the electrical converter; comparing the error value with an error band and in the case of the error value exceeds the error band, controlling the electrical converter by switching to a different control scheme. The converter is controlled with the modified pre-calculated switching by determining a pre-calculated switching sequence for the converter based on an actual state of the electrical converter, the switching sequence comprising a sequence of switching transitions of the converter; modifying the pre-calculated switching sequence by modifying transition times of switching transitions of the pre-calculated switching sequence, such that the error value is minimized; and applying at least a part of the modified switching sequence to the electrical converter.

Abstract: A method for controlling a modular converter with a plurality of converter modules includes: selecting possible future switching sequences of the converter based on an actual converter switching state; predicting a future current trajectory for each switching sequence based on actual internal currents and on actual internal voltages; and determining candidate sequences from the switching sequences, wherein a candidate sequence is a switching sequence with a current trajectory that respects predefined bounds with respect to a reference current or, when a predefined bound is violated, moves the current closer to such a predefined bound. The method includes predicting future module voltages for each candidate sequence; evaluating a cost function for each candidate sequence; and selecting the next converter switching state as a first converter switching state of a candidate sequence with minimal costs.

Abstract: An exemplary electrical converter includes a plurality of semiconductor switches. The electrical converter is configured for generating a two-level or multi-level output voltage from an input voltage by switching the plurality of semiconductor switches. A method for controlling the electrical converter includes receiving a reference electrical quantity (iS*) and an actual electrical quantity (iS), determining a sequence of future electrical quantities of the electrical converter from the actual electrical quantity, determining a maximal cost value based on the sequence of future electrical quantities, and iteratively determining an optimal switching sequence for the electrical converter. A switching sequence includes a sequence of future switching states for the semiconductor switches of the electrical converter. The method also includes selecting the first switching state of the optimal switching sequence as the next switching state (u) to be applied to the semiconductor switches of the electrical converter.
