Abstract: An exemplary method for controlling an electrical converter includes receiving an actual electrical quantity relating to the electrical converter and a reference quantity; determining a future state of the electrical converter by minimizing an objective function based on the actual electrical quantity and the reference quantity as initial optimization variables; and determining the next switching state for the electrical converter from the future state of the electrical converter. The objective function is iteratively optimized by: calculating optimized unconstrained optimization variables based on computing a gradient of the objective function with respect to optimization variables; and calculating optimization variables for a next iteration step by projecting the unconstrained optimization variables on constraints. The computation of the gradient and/or the projection is performed in parallel in more than one computing unit.
