摘　　要：本论文建立了以典型MRAS转速识别理论为基础的仿真模型,进行仿真。同时分析了在实际情况下,典型MRAS转速识别受电机参数变化和定子电流干扰等因素影响所存在的不足,考虑到定子电阻的变化与定子电流干扰这两个主要因素的影响,通过仿真实验证明了改进型MRAS速度辨识模型具有较好的控制精度和动态性能。This paper is to introduce a simulation model that is simulated on the basis of rotating speed identification system under typical MRAS （ Model Reference Adaptive System）, and effects from some factors are being analyzed under actual circumstances, such as changes of motor parameters of typical MRAS speed identification and interference of stator current. And it shows, the improved model of MARS non - speed sensor vector control is more accurate and has a better dynamic performance as the two main factors, changes of stator resistance and interference of stator current, have been taken into consideration in simulation experiments.
