High accuracy and parameter robust multi-vector model predictive control for 10-tube neutral point clamped hybrid active power filter

• A 10-tube T-NPC-HAPF with reduced components is proposed. • An ultra-local model with NDO removes capacitor voltage sensors. • An ODC-MPC ensures volt-second balance and high accuracy. • A simplified multi-vector strategy reduces computation cost. • Experiments validate low THD and strong robustness.
