A FCS-MPC with delayed switching for a two-level voltage source inverter

This paper proposes a modified FCS-MPC strategy for voltage source inverters (VSI), which can achieve a better voltage tracking performance than traditional MPC with limited computation burden. Instead of immediately switching at the beginning of the control period, the proposed method will delay the switching action, which actually combines the present state and the next optimal switching state for better tracking performance. As such, the suppression of total harmonic distortion (THD) gets improved. Without additional state traversal, the delaying time computation burden is limited. In simulation test, the efficactiveness is confirmed by the VSI of proposed strategy.
