To address the computational burden associated with traditional model predictive control strategies when a permanent magnet synchronous motor (PMSM) is driven by three-level converters, an optimization strategy is proposed. First, a discretized model of the PMSM is developed. Second, the Nelder-Mead algorithm is applied to the selection of optimal voltage vectors for the three-level converter, iteratively seeking the voltage vector that minimizes the current control errors. Finally, the output voltage vector is determined in conjunction with the DC-side capacitor voltage. The proposed optimization strategy involves a maximum of seven current predictions within a control cycle. Experimental validation demonstrates that compared with the traditional model predictive control strategy, the proposed optimization strategy reduced the computation time by approximately 45%, without compromising the steady-state control performance. Moreover, this strategy exhibited excellent DC-side capacitor voltage balancing capability.
