【摘要】 多相电机控制是一个多维控制问题,但目前大多数多相电机的控制方法仍然是三相电机控制方法的简单推广,导致了谐波电流不可控、系统性能低等问题。在详细分析了多相电机数学模型和多相空间电压矢量分布特征的基础上,本文采用基于正交矢量空间的多维控制方法,实现了多相电机电流的多维调节。全文以五相永磁同步电机驱动系统为例,仿真和试验结果表明了该方法的有效性。更多还原

【Abstract】 Multiphase motor is a multi-dimensional driving system. However, some control strategies simply extending those of three-phase drives would result in undesired harmonics, low performance and other problems. By analyzing the multiphase motors model and the characteristics of multiphase motor, a novel current adjust method is developed. A five-phase PMSM driving system is demonstrated in this paper. Simulations and experimental results verify the theoretical concepts.更多还原
