摘要
建立了按转子磁场定向的异步电机数学模型,基于转差频率矢量控制的原理,以电机控制专用数字信号处理器TMS320F240为核心,开发了一套全数字化异步电机矢量控制系统,采用空间矢量脉宽调制方法以提高直流电压的利用率。试验结果表明,该控制系统具有良好的动、静态性能。
The mathematics model of the asynchronous motor based on the rotor flux oriented was founded. A full-digital slip frequency vector controlled asynchronous motor system was built by the motor controlled digital processor TMS320F240. SVPWM was adopted to heighten the utilization ratio of the DC voltage. The experiment results show that this control system had good dynamic and static performances.
