摘　　要：针对众多文献资料经常用到矢量控制技术却很少提到矢量控制技术中调节器设计的具体实现问题,提出矢量控制系统的解耦及调节器设计的具体工程实现方法和实现过程。简要阐述异步电机按转子磁链定向的数学模型和SVPWM技术,并在矢量控制原理的基础上,利用MATLAB/Simulink进行矢量控制模型的仿真。由测试结果可以看出,转速具有跟随特性,并验证了矢量控制的优越性:可以实现与直流电机相近的调速特性。测试结果也表明提出的调节器工程设计方法具有适用性。Since vector control is mostly used in a lot of documentation without often mentioning concrete design of the regulator, this paper presents a specific implementation method and process for the design of decoupling and regulator of the vector control system. It briefly describes the mathematical model for orientation of the asynchronous motor according to the rotor flux linkage and SVPWM technology, and on the basis of the vector control principle, uses MATLAB / Simulink to simulate the vector control model. The result of the test shows that the rotational speed has the characteristic to follow, and superiority of vector control is also verified ： it can realize similar speed regulation as a DC motor. The test results further indicate that the proposed regulator design method has applicability.
