Abstract
Disclosed herein is a method for controlling an electrical converter system that includes: determining a nominal pulse pattern (t*, Δu*) and a reference trajectory (x*) of at least one electrical quantity of the electrical converter system over a horizon of future sampling instants, the nominal pulse pattern (t*, Δu*) comprises switching transitions (Δu*) between output voltages of an electrical converter of the electrical converter system and the reference trajectory (x*) indicates a desired future development of an electrical quantity of the converter system; determining a small-signal pulse pattern (ũ(t, λ)) by minimizing a cost function; determining a modified pulse pattern (t, Δu) by moving the switching transitions of the nominal pulse pattern (t*, Δu*) to generate modified switching transitions; and applying at least the next switching transition of the modified pulse pattern (t, Δu) to the electrical converter system.
