60°坐标系下三电平感应电机SVPWM算法

SVPWM Algorithm for Three-level Induction Motor in 60° Coordinate System

传统三电平正交坐标系下空间矢量脉宽调制法(SVPWM)在矢量合成过程中,涉及大量函数运算,计算复杂,占用了计算机大量存储空间、导致运算效率下降。为更好的实现编程控制,进行60o坐标系下的SVPWM算法研究,改进和简化传统的SVPWM算法,避免了计算过程中大量的逻辑运算。最后通过对系统进行仿真分析与实验平台验证,结果表明,该算法减少了运算时间,提高了计算精度,更能满足实际工况需求。

As involving a large number of trigonometric functions, the space vector pulse width modulation （SVPWM） based on traditional three-level orthogonal coordinate system is complex in calculation, resulting in redundant storage, low efficiency, long operation time and so on. For better programming control, SVPWM algorithm based on 60° coordinate system is studied, improved and simplified, and a large number of logical operations are avoided in the calculation process. The simulation analysis of the control system and experimental platform validation are completed, and the results show that the algorithm reduces the operation time, improves the computing accuracy and meets the requirements of actual working condition.
