Abstract This paper proposes an on-line maximum torque per ampere (MTPA)/maximum torque per voltage (MTPV) trajectory tracking method in permanent magnet synchronous machines (PMSMs) with power management. The on-line MTPA/MTPV machine current trajectory tracking algorithm is developed from PMSM model. Maximum source current and machine current are regulated to enhance hardware protection during machine current trajectory tracking. The maximum source current management is achieved by iterating within the current trajectory tracking algorithm over continuous torque command modifications based on power flow analysis, and the maximum machine current management is achieved by torque command limiting based on current angle modulation. Different from the existing techniques in literature, the proposed method has an unique feature of providing on-line regulation of source current, while maintaining on-line MTPA/MTPV trajectory tracking in PMSMs. It also provides machine and inverter overcurrent regulation to enhance their protection. In addition, the proposed method is flexible to tune and does not require off-line calibration. The effectiveness of the proposed method is confirmed by simulation results in MATLAB.

带电源管理的永磁同步电机在线MTPA/MTPV轨迹跟踪仿真研究

摘要 本文提出了一种具有功率管理的永磁同步电机 (PMSM) 中的在线最大每安培扭矩 (MTPA)/每电压最大扭矩 (MTPV) 轨迹跟踪方法。在线MTPA/MTPV机器电流轨迹跟踪算法是从PMSM模型发展而来的。调节最大源电流和机器电流以增强机器电流轨迹跟踪期间的硬件保护。最大源电流管理是通过在电流轨迹跟踪算法内迭代基于功率流分析的连续扭矩命令修改来实现的，而最大机器电流管理是通过基于电流角调制的扭矩命令限制来实现的。与文献中现有的技术不同，所提出的方法具有提供源电流在线调节的独特功能，同时在 PMSM 中保持在线 MTPA/MTPV 轨迹跟踪。它还提供机器和逆变器过流调节以增强它们的保护。此外，所提出的方法调整灵活，不需要离线校准。在MATLAB中的仿真结果证实了该方法的有效性。
