摘要
将转矩预测控制策略应用于单逆变器供电的双并联永磁同步电机驱动系统,通过分析双机系统运行特点,并对两电机的转矩和磁链预测进行统一规划,实现了在一个价值函数中对双永磁同步电机的灵活控制。所提方法具有很好的同步稳定性,即使在负载转矩不同情况下,仍然能够确保两个电机获得相同的转速。最后利用MATLAB软件进行了仿真实验,其结果验证了该方法的可行性和有效性。
A torque predictive control algorithm was presented for controlling system composed by two permanent mag- net synchronous motors operating in parallel, fed by a single inverter. By analyzing the operating characteristics of dual mo- tor system and planning the predicted torque and predicted flux, dual parallel PMSM system was controlled flexibly in one cost function. The proposed method has good stability synchronization, even under different load torque conditions, the two motors can be ensured to obtain the same rotational speed. Finally, simulation experiments were implemented via MATLAB software. The results show that the proposed method is valid and feasible.
