| 摘要: |
| 矢量控制技术作为交流异步电机控制的一种方式已成为高性能变频调速系统的首选方案，空间矢量脉宽调制SVPWM（Space Vector Pulse Width Modulation）方式因具有比SPWM调速方式更优异的性能而得到了广泛应用．简要介绍了电压空间矢量脉宽调制和矢量控制的基本原理，运用TI公司面向电机控制推出的新一代数字信号处理器芯片TMS320LF 2407．提出了一种实现SVPWM方法．并给出了变频调速系统的全数字化实现。通过对实际电机进行控制实验，得到的结果表明此方法是切实可行的．控制系统具有优良的动静态性能、较高的控制效果，有广泛的应用前景． |

| Abstract: |
| Vector control technology is widely used in high-performance variable-frequency speed-go-verning system to control the AC asynchronous machine.Compared with SPWM,SVPWM(Space Vector Pulse Width Modulation) has better performance.The basic principle of voltage SVPWM and field oriented control is introduced briefly.A full-digital solution with TMS320LF 2407 of TI using SVPWM control method is presented.The result of experiment with practical motor indicates that the proposed method is feasible and the control system has excellent dynamic and static performances and high control effect. |
