| 摘 要： | 介绍了空间矢量脉宽调制的基本原理及实现方法,利用Matlab对空间矢量脉宽调制(SVPWM)和正弦脉宽调制(SPWM)进行仿真研究,得到系统运行的理论波形。最后用DSP电机控制芯片TMS320LF2407A实现了空间矢量脉宽调制算法,给出了相应的结果。仿真和实验结果表明空间矢量脉宽调制方案正确可行,减少了系统的纹波,提高了系统的控制精度,而且算法简单,实现方便。

| Abstract: | On the basis of the principle of space vector pulse width modulation of the three phase AC motor,simulation of space vector pulse width modulation and sine pulse width modulation are analysized,space vector pulse width modulation are implemented and experiment results are achieved,which are based on an integrated DSP motor controller TMS320LF2407A.The simulation by Simulink in Matlab is discussed,and the model of PMSM is built.With the model of PMSM and arithmetic of SVPWM,the wave of the theory is obtained.Software of the space vector PWM is worked out. |
