以TMS320F2812型DSP为控制核心，搭建了异步电机电压空间矢量脉宽调制（SVPWM）控制系统。通过对异步电机控制原理的分析，本文中用Matlab／Simulink平台对异步电机矢量控制系统进行仿真，完成了三相异步电机矢量控制系统硬件和软件设计。最后详细介绍了SVPWM控制系统的调试过程，并完成了异步电机调速系统的研究。

By taking the DSP of TMS320F2812 as the control core, the voltage space vector pulse width modulation（SVPWM） control system for asynchronous motor is set up. By means of analyzing the control principle of asynchronous motor, the platform of Matlab/Simulink is used for simulating the vector control system of asynchronous motor and the hardware and software designs of the vector control system for the three-phase asynchronous motor are achieved in this paper. Finally, the debugging processes of the SVPWM control system are introduced in detail, and the research of the asynchronous motor speed control system is completed as well.
