摘要: 针对永磁同步电机在弱磁运行过程中因参数变化导致的控制性能下降问题,提出了一种采用单q轴电流调节器的多参数自适应补偿控制策略,以提高电机在弱磁区域内的转矩控制精度。实验结果表明该方法对参数的辨识误差在5%以下,输出转矩与期望转矩的误差小于1%,该方法能有效地抑制多参数变化对电机性能的影响。

Abstract: In order to enhance the control performance of permanent magnet synchronous motors with parameter variations under field weakening operations, a multi-parameter adaptive compensation control method was proposed based on the single q-axis current regulator. The experimental results show that the identification error for parameters is less than 5%, and the error between the torque output and the torque reference is less than 1%, indicating the proposed method can effectively suppress the influence of multi-parameter variations.
