| 摘 要： | 空间矢量脉宽调制(Space Vector Pulse Width Modulation,SVPWM)是控制交流异步电动机的一种控制方式。SVPWM技术应用于交流调速系统,不但改善了脉宽调制(Pulse Width Modulation,PWM)技术存在电压利用率偏低的缺点,而且具有转矩脉动小、噪声低等优点。笔者给出了以TMS320LF2407A型DSP芯片为控制电路核心的交流异步电动机SVPWM矢量控制调速系统,并分析了其SVPWM技术的实现方法。试验结果表明,该调速系统具有较好的动、静态特性,从而验证了SVPWM控制方法的可行性和有效性。

| Abstract: | Space vector pulse width modulation(SVPWM) is a method of controlling the AC induction motor.Application of SVPWM technology in AC speed regulation system not only improves the shortcomings of low voltage utilization rate in the pulse width modulation(PWM) technology,but possesses advantages such as little torque ripple and low noise etc.The paper offered a SVPWM vector control system with TMS320LF2407A-type DSP chip serving as the core of the control circuit for speed regulation of the AC induction motor,and analyzed the realization method of SVPWM technology.The test results indicated that the proposed speed regulation system had excellent dynamic and static performance,and the feasibility and effectiveness of the SVPWM control method were verified. |
