    • A method for controlling an electrical converter (12) comprises the steps of: determining an error value (ψ s,err ) based on a difference between an estimated output value (ψ s ) and a reference output value (ψ s *), the estimated output value being based on measurements in the electrical converter (12); comparing the error value (ψ s,err ) with an error band (46a) and in the case of the error value exceeds the error band (46a), 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 (40) for the converter (12) based on an actual state of the electrical converter (12), the switching sequence comprising a sequence of switching transitions (42) of the converter (12); modifying the pre-calculated switching sequence (40) by modifying transition times of switching transitions (42) of the pre-calculated switching sequence, such that the error value (ψ s,err ) is minimized; and applying at least a part of the modified switching sequence to the electrical converter (12).
