摘　　要：通过盘式永磁同步电动机相对异步电动机所具有的一些良好特性结合在油田的实际应用情况,研究了一种基于矢量控制的模型参考自适应盘式永磁同步电机无速度传感器控制方法。对其无速度传感器矢量控制进行研究。依据永磁同步电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在线辨识的方法,该方法为盘式永磁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。Permanent magnet motor through the disc by the relatively asynchronous motor with some good characteristics of the oilfield in the practical application of their speed sensor vector control research. Based on permanent magnet synchronous motor in synchronized rotation coordinates of the stator current model, based on the theory MRAS a neural network on-line identification methods, the method for the disc permanent magnet motor speed sensor-control strategy to provide a new choice. Theoretical analysis and simulation results show that the neural network-based MRAS speed online identification method is effective and feasible.
