摘要:
 摘要:针对传统双三相电机空间矢量脉冲宽度调制(space vector pulse width modulation , SVPWM )算法中含有大量的三角函数和求根运算,且电机定子电流谐波含量大的问题。结合双三相电机的矢量分类技术,在120。的非正交坐标系下提出了一种双三相感应电机的空间矢量脉冲宽度调制算法。判断三相给定电压信号的最大值和最小值,通过总结规律,可直接求得各相开关的切换时刻,无须进行扇区和基本电压矢量作用时间的计算。对仿真和实验结果的分析表明,与传统双三相SVPWM算法相比,所提出的双三相感应电机SVPWM算法可以有效抑制电机定子电流谐波的同时,大大缩短算法执行时间。定子电流谐波的抑制可提高电机控制性能,算法执行时间的缩短将为处理器节约资源。
Abstract:
 Abstract:To address the traditional space vector pulse width modulation algorithm of dual three-phase motor which contains a large number of trigonometric functions and finding roots of computing,and the motor stator current contains a large number of harmonic components,combined with dual three-phase mofor vector classification,a dual three-phase induction motor space vector pulse width modulation algorithm was proposed in non-orthogonal coordinate system of 1200. The maximum and minimum values of given three-phase voltage signals were determined. There is no need to calculate the sector and the role of the fundamental voltage vector time , and it can directly obtain switching time with each phase by summarizing the law. The simulation and experimental results show that compared with conventional dual three-phase SVPWM algorithm,the novel dual three-phase induction motor SVPWM algorithm effectively inhibits the motor stator current harmonics,while greatly reducing the execution time of the algorithm. Stator current harmonic suppression improves motor control performances,and shorten the execution time of the algorithm which saves processor resources.
