基于模型参考自适应系统的永磁电机转子无位置传感控制

PMSM Adaptive Sensorless Control based on MRAS

以永磁同步电动机的三相坐标系下的数学模型为基础，增加估计坐标系并建立出此坐标系下的永磁同步电动机的数学模型，并在此方程下利用POPOV超稳定理论导出自适应率，从而提出了一种运算简单且具有良好性能的基于模型参考自适应系统的永磁同步电动机无位置传感器控制方法。在Matlab／Simulink中构建该系统的仿真模型，进行仿真实验，通过实验验证了该方法具有良好的控制性能。

Based on Mathematical model of permanent magnet synchronous motor of three-phase coordinate system,to increase an estimated coordinate system and build new mathematical model of permanent magnet synchronous motor,and then use the POPOV hyperstable theory derived adaptive rate, present a good permanent magnetic model reference adaptive sensorless control method,which have simple calculations and good performance. Constructing the simulation model of the system in the Matlab/Simulink, by simulation experiments, show that the method has good control performance.
