摘要
依据永磁同步电动机在同步旋转坐标系下的定子电流数学模型,基于MRAS理论提出一种神经网络转速在线辨识的方法,该方法为永磁同步电动机无速度传感器的控制策略提供了新选择。理论分析及仿真结果表明基于MRAS的神经网络转速在线辨识方法的有效性和可行性。
According to permanent magnet synchronous motor (PMSM) stator current mathematical model under synchronous rotation coordinates, a speed on - line identification method based on MRAS was presented in this paper. This method provided a new choice for the PMSM sensorless control strategy. Theoretical analysis and simulation results showed the effectiveness and feasibility of the method.
