摘要：针对永磁同步电机应用中的电流环PI调节器存在的dq轴电流的交叉耦合现象，影响到电流环响应速度与解耦效果，进而影响伺服系统外环的动态响应速度问题，本文提出了一种利用转速微分与电流环PI调节器相结合的动态解耦策略。并通过Matlab/Simulink仿真和基于DSP试验平台进行验证试验。研究结果表明：本文所提出的的电流动态解耦方法，能有效抑制dq轴之间的动态耦合现象，改善了电流的跟随性。

Abstract: The crosscoupling phenomenon of dqaxis current in the current loop PI regulator for permanent magnet synchronous motor applications affects the response speed and decoupling of the current loop, and then affects the dynamic response speed of the outer loop of the servo system. This paper presented a dynamic decoupling strategy that combines rotational speed differentials with current loop PI regulators. And through the Matlab/Simulink simulation and DSPbased test platform for verification tests. The results show that the current dynamic decoupling method proposed in this paper can effectively suppress the dynamic coupling between the dq axes and improve the current followability.
