摘要
叙述了电压空间矢量脉宽调制(SVPWM)的基本原理、介绍了一种以DSP 56F8346为核心的异步电动机调速系统的软件设计。介绍了空间电压矢量产生的软件流程。实验结果表明电压空间矢量调制的正确性,该系统实现算法简单、控制精度高、输出电流谐波失真小、有较强的实时性。
The paper describes the basic principle of the space vector pulse width modulation（SVPWM）,the software design of digital controller based on DSP56F8346 for AC induction motor is introduced. The software flow about SVPWM is described. The experimental results indicate correctness of SVPWM and the prototype has simpler software design, higher control precision, less output current harmonics distortion and better real - time performance.
