【 摘 要 】

Objectives In view of the problem of multi-parameter setting and strategy complexity under the traditional control strategy, a modular multi-level converter (MMC) model predictive control method for the electric propulsion drive system of a ship is proposed. Methods First, the complexity of driving system design under the traditional control strategy is analyzed. Next, based on the advantages of model predictive control, a corresponding MMC model predictive control strategy is designed for the electric propulsion drive system of a ship. Finally, in a Matlab/Simulink environment, a 3.3 kV/20 MW permanent magnet synchronous motor (PMSM) driving system model with propeller load is built, and the control strategy is simulated and verified. Results Through simulation, the designed MMC model predictive control method can maintain the static difference of the motor speed within 1% and reduce torque ripple by 6.1%, indicating that the proposed control method is feasible and has certain advantages. Conclusions The results of this study can provide valuable references for the MMC design of medium-voltage DC electric propulsion systems of ships.
