Abstract: In a method based on the MPDTC algorithm for controlling an inverter of an electrical system, the harmonics and resonances in the inverter can be damped by extracting frequency information from predicted data of the MPDTC algorithm and by damping harmonic distortion of the electrical system by reintroducing the extracted frequency information into a control loop of the inverter.
