摘要
介绍了空间矢量脉宽调制的基本原理及实现方法,使用了其中的SIMULINK工具箱建立了永磁同步电机的数学模型,用MATLAB进行了仿真。根据SVPWM算法和永磁同步电机的模型,得到系统运行的理论波形。最后使用TMS240F2407DSP芯片实现空间矢量脉宽调制,并利用泰克示波器测出了实际的结果波形,TMS320F2407是美国TI公司专为数字电机控制应用而推出的一种低价格、高性能的DSP内核和丰富的外设功能集于一身的微控制器。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。
Space vector pulse width modulate which is a new way of modulation. It has superiority with sine pulse width which bring the magnetic field roundness and reduce the pulse of voltage. The principle of space vector PWM of three-phase AC motor and it is implementation are introduced. In this paper,The simulation by Simulink in MATLAB is discussed,and the model of PMSM is build. 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 and correlated experiment results are achieved,which is based on an DSP motor controller TMS320LF2407 in the end. TMS320LF2407 is a good way which has low-price, high-performance of core with DSP and so on. It reduces the veins of system, and improves the precision of the control.
