摘要
分析了交流永磁同步电机矢量控制中Id,Iq与ud,uq之间的交叉耦合关系,采用内模控制原理对其进行解耦并应用于交流永磁同步电机矢量控制中,采用DSP实现内模电流解耦控制,并进行了硬件、软件实验平台的设计。实验结果表明,与传统的矢量控制方法相比,采用内模控制解耦的矢量控制方式具有更良好的控制特性。
The coupling effects between Id, Iq and ud ,uq in the vector-control strategy of PMSM （permanent magnet synchronous motor）was analyzed. A new control strategy of using the internal model control theory to decouple the system and apply the new control strategy into the vector-control of PMSM was proposed. The experimental platform using DSP and design the hardware and software of the system was established. The experiment shows that it has more excellent performance than traditional vector-control strategy.
