摘要
针对于双Y移30°永磁同步电动机(Permanent Magnet Synchronous Motor,简称PMSM)提出了一种新颖的空间矢量脉宽调制(Space Vector Pulse Width Modulation,简称SVPWM)技术,用直观且简单的方法分析了定子线圈中存在的高次谐波,推导出了谐波电流有效值的平方与调制指数的关系式。构造了基于低功耗定点数字信号处理器TMS320F2812的7.5kW双Y移30°PMSM控制系统。实验验证了提出方法的正确性和可行性。
A new space vector pulse width modulation（SVPWM）technique for the dual Y shift 30° permanent magnet synchronous motor（PMSM）is presented.Intuitive and straightforward approach for analytical investigation of the harmonic characteristics in the stator windings lend to analytical formulas of square rms harmonic current and modulation index.This PMSM control system is set up based on a low-cost fixed-point TMS320F2812 digital signal processor.The experimental results demonstrate the effectiveness and feasibility of the proposed method.
