| 摘 要： | 鉴于空间矢量脉宽调制法(SVPWM)诸多优点,如果能对其先进行一些仿真研究必定会给它的应用实践带来不少裨益.由此,首先对SVPWM技术原理的进行了介绍,特别对其线性组合法五段式SVPWM波形的实现方法进行了详细的讨论.其次,在MATLAB/SIMULINK环境下,把这种SVPWM实现方法放入了一个开环异步电动机变频调速系统中进行了应用仿真.通过对定子电压与磁链的相位关系、磁链对圆的逼近及过调制现象三个重要内容的仿真研究,结果表明与理论分析都很一致,从而为SVPWM技术的实际应用及研究提供了一定的参考价值.

| Abstract: | In view of the advantages of SVPWM,if some computer simulations about it could be done,it will be very useful for its practical application.Therefore,this paper introduces the principles of space vector PWM at first, especially discusses how to realize the five-section SVPWM waveform of the method of linear construction in detail, which is one of the methods of SVPWM construction.Besides,under MATLAB/SIMULINK,the open-loop Asyn- chronous Machine control system based on SVPWM is simulated.Three important contents(the phase relation be- tween stator voltage and magnetic flux,the magnetic flux of stator approximating a round and SVPWM overmodula- tion)are simulated,and the gotten simulation results all accord with theoretical analysis.So,this paper may be re- ferred by others. |
