对常规MRAS转速辨识进行了分析，针对异步电机无速度传感器矢量控制提出了一种改进型MRAS转速辨识方法。通过设计一个基于转子磁链定向电流模型下的补偿器，用于对磁链观测进行幅值和相位的实时补偿。仿真和实验表明，经过改进后的转速MRAS辨识方法具有较高的转子磁链观测精度，改善了转速估计的动静态性能，提高了系统的鲁棒性。

By theoretical analysis on the common model reference adaptive speed identification system ( CM-RAS) , a method of improved MRAS ( IMRAS) was proposed for speed identification of a sensorless vector control system.In this strategy, a flux observer compensator was designed for compensating the flux ampli-tude and phase based on the current model in the rotor flux orientation.The simulation and experiments re-sults showed that the IMRAS possessed the veracity of flux observers, improved the dynamic and static per-formance of the speed estimation and increased the robustness of system.
