五桥臂双永磁同步电机系统优化模型预测控制
|
摘要
五桥臂逆变器传统模型预测控制一个控制周期内由单矢量作用,降低了2台电机的运行性能。针对该问题,提出了优化模型预测控制策略。通过对2台电机有效电压矢量和零电压矢量的占空比进行整体优化分配,减小电机的转矩波动,提高2台电机的控制精度,进而在满足2台三相电机控制独立性的情况下,提升了电机系统的控制性能。仿真结果验证了所提优化模型预测控制的正确性和有效性。
The traditional model predictive control for dual permanent magnet synchronous motor system driven by five-leg inverter reduced the control accuracy of the two motors due to the single vector action in one control cycle. Aiming at this problem, an optimization model predictive control strategy was proposed. By distributing the duty cycles of the active voltage vector and the zero voltage vector of the two motors, the torque ripple was reduced to improve the control precision of the two motors, and then the control performance of the motor system was improved while satisfying the control independence of the two three-phase motors. The feasibility and effectiveness of the proposed optimal model prediction control were verified by simulation results.
