SVPWM异步电机矢量控制模型，适合初学者学习的异步电机矢量控制模型(Vector control model of SVPWM asynchronous motor)

说明：  DSP本身在内的所有电子器件都是干扰源，而且系统所处的工作环境中还有很多外来干扰源，再加上语音识别技术对信号噪声非常敏感，所以在系统设计中必须考虑系统的抗干扰问题。(DSP itself, including all electronic devices are sources of interference, and the system environment in which there are many external sources of interference, coupled with voice recognition technology is very sensitive to signal noise, so the system design must consider the system of anti- interference problem.)
