摘要：本文针对永磁同步电机在实际运行中的不稳定问题，提出了一种基于电流反馈控制结构的简单自适应内模型。实际的永磁同步电机控制系统是一个时变系统，内模型根据电机系统不同的运行状态选择合适的不确定性估计函数。随后，在控制系统中建立以不确定估计函数为基础的频率模型，并以鲁棒电流的形式完成对系统的控制。此外，这种不确定性估计函数模型，也为永磁同步电机转矩波动抑制提供了一个有效地解决方案。频率模型还能抑制在稳定闭环系统中的谐波干扰，这是因为根据不同的谐波干扰内模型能建立相应的频率模型。为了得到一个大带宽的不确定性估计，利用李雅普诺夫函数和电流动力学方程推导出了一个简单的自适应函数。通过对比不同系统在该控制方案下的控制效果，可以看出本文提出的控制策略是十分有效地。
