| 摘 要： | 介绍了一种交流异步电机无速度传感器矢量控制实现方案。该方案结合了传统的电流和电压磁链观测方法的优点,采用改进的磁链观测方法,在电机高速和低速运行时都能准确地观测磁链,从而估算出电机速度,实现无速度传感器的矢量控制。该实现方案基于高性能数字信号处理器TMS320F2806。试验表明,它在高速和低速段都其有较好的性能。

| Abstract: | A sensorless vector control method for AC motor is discussed in this paper. A new advanced rotor flux estimated method which combine the advantages of traditional voltage method and current method is adopted while can achieve high accuracy in,high speed or Iow gpeed region. The control algorithms has been implemented on a high performance TMS320F2806 DSP of Texas Instruments. Experimental results show that this method has good performance. |
