| Abstract |
For finite-control-set model predictive control with long horizons, a method is proposed that allows targeted harmonics in the current spectrum to be suppressed. The method involves adding band-pass filters at target frequencies, which are then included in the state-space representation of the prediction model. The underlying optimization problem can be efficiently solved with sphere decoding, allowing the use of long horizons to improve the system performance. A case study with a grid-connected converter is presented and simulations are provided that demonstrate the efficacy of the proposed method. |
