摘　　要：针对电机实验站对永磁同步电机实验电源系统新的控制要求,研究了M W级永磁同步电机无速度传感器矢量控制方法,提出了一种基于模型参考自适应的速度辨识方法。该方法仅用q轴磁链误差信号构建自适应率辨识转速信息。首先通过Matlab仿真证明了该方法的有效性,然后进行了半直驱隐极式永磁同步风力发电机对拖实验,结果证明该方法能较好地辨识电机转速。For the new control demands of permanent magnet synchronous motor（PMSM） experimental power sup- ply system, speed sensorless vector control method of MW Turbine PMSM was researched, and a new speed estimation method based on model reference adaptive system （MRAS） was proposed. In the method, the q-axis flux error signal was used to construct adaptive rate and estimate the speed. First by Matlab simulation the validity of the＇method was proved, then the test of two halfdirect permanent magnet synchronous generators towed each other was made. The result of the experiment shows that the method has a good speed estimation effect.
