摘要

有限控制集模型预测电流控制(FCS-MPCC)方案具有实现简单、动态响应快等优点，在机械传动中得到了广泛的应用。然而，定子电流的低次谐波、繁重的计算负担和直流电压的利用率提高是FCS-MPCC多相电机驱动方案的关键问题。因此，本文提出了一种具有优化占空比(MPCC-ODR)的五相电机驱动FCS-MPCC方案。仿真和实验结果验证了所提出的MPCC-ODR方案能够抑制低阶谐波，提高直流链路电压利用率，降低计算复杂度。

A Finite Control Set Model Predictive Current Control Scheme for Five-phase PMSMs Based on Optimized Duty Ratio

Finite control set model predictive current control (FCS-MPCC) scheme is easy to realize and has fast dynamic response, so it’s widely employed in machine drive applications. However, the low-order harmonics in stator currents, heavy computation burden and the utilization improvement of dc-link voltage are the key issues of FCS-MPCC schemes for multiphase machine drives. Thus, this paper proposes a FCS-MPCC scheme with the optimized duty ratio (MPCC-ODR) for five-phase machine drives. Simulations and experimental results have verified that the proposed MPCC-ODR scheme can suppress low-order harmonics, improve the utilization of dc-link voltage and reduce computation complexity.
