This paper investigates a high-performance finite-set model predictive control (FS-MPC) based on an optimal switching voltage vector technique for voltage-source inverter (VSI)-fed interior permanent magnet synchronous motor (IPMSM) drives. The proposed algorithm clamps one switch that supplies the largest phase current at each sampling interval while allowing the other two pole switches to remain active. Unlike the conventional FS-MPC scheme, the proposed scheme involves only two voltage vectors to obtain an optimal switching state with reduced switching losses and low computational cost without incorporating any additional parameters or constraints in the cost function. Thus, the proposed FS-MPC implemented on a DSP-based prototype exhibits high performance features (low switching losses and low harmonic distortion above rated speed) in constant torque and power regions. The experimental results on prototype VSI-fed IPMSM with TMS320F28335 are presented under various conditions to demonstrate the efficacy of the proposed scheme compared with the conventional FS-MPC.

高性能IPMSM驱动应用的具有最佳开关电压矢量技术的有限集模型预测控制方案

本文研究了基于最优开关电压矢量技术的高性能有限集模型预测控制（FS-MPC），用于电压源逆变器（VSI）供电的内部永磁同步电动机（IPMSM）驱动器。提出的算法钳位一个开关，该开关在每个采样间隔提供最大的相电流，同时允许其他两个极点开关保持活动状态。与传统的FS-MPC方案不同，所提出的方案仅涉及两个电压矢量，以获得具有降低的开关损耗和较低的计算成本的最佳开关状态，而无需在成本函数中包含任何其他参数或约束。因此，在基于DSP的原型上实施的拟议FS-MPC在恒定转矩和功率区域具有高性能（低开关损耗和低于额定速度的低谐波失真）。在各种条件下给出了带有TMS320F28335的由VSI馈送的IPMSM原型的实验结果，以证明与传统的FS-MPC相比，该方案的功效。
