摘要

为了解决开绕组共直流母线永磁同步电动机(low - pmsm - cdcb)逆变调制过程中出现的三、五、七次谐波问题。本文在传统比例-积分(PI)和比例-谐振(PR)控制的基础上，研究了一种适用于不同转速条件下的改进比例-积分-谐振(QPIR)谐波抑制方法。实现了三、五、七次谐波跟踪，解决了转速变化时PR控制不能改变的问题。给出了QPIR的稳定性证明和参数选择。最后，搭建了OW-PMSM-CDCB驱动系统实验平台进行验证。仿真和实验结果表明，QPIR控制策略能有效抑制低阶pmsm系统在不同转速下的三、五、七次谐波。

Harmonic Suppression of Open-Winding PMSM System with Common DC Bus Based on Improved PIR Control

In order to solve the problem of 3rd, 5th and 7th harmonics in the inverter modulation process of Open-Winding Permanent Magnet Synchronous Motor with Common DC Bus (OW-PMSM-CDCB). In this paper, with the help of traditional Proportional-Integral (PI) and Proportional-Resonant (PR) control, an improved Proportional-Integral-Resonant (QPIR) harmonic suppression method which can be applied to different speed conditions is studied. The 3rd, 5th and 7th harmonics tracking are realized to solve the problem that PR control cannot change with the speed change. The stability proof and parameter selection of QPIR are given. Finally, an OW-PMSM-CDCB drive system experimental platform was built for verification. Simulation and experimental results show that the QPIR control strategy can effectively suppress the 3rd, 5th and 7th harmonics of the OW-PMSM system at different speeds.
