基于SVPWM的变频调速系统的研究与仿真
Research and Simulation on Frequency Conversion Speed Regulation System with SVPWM
文章详细介绍了空间电压矢量脉宽调制（SVPWM）技术的基本原理，设计了以DSP芯片型号为TMS320F240PQ为控制器的SVPWM变频调速系统，介绍了该系统的硬件构成和软件实现，并用Matlab/Simulink软件对该系统进行了仿真实验。实验结果验证了该文所建立的调速系统可以实现异步电动机产生转矩的电流分量和产生磁通的电流分量之间的解耦控制，使电机获得与他励直流电机一致的瞬态响应特性，并且该系统具有启动快、超调小、稳态转矩脉动小等特点。
The paper analyzed principle of voltage space vector pulse width modulation (SVPWM),designed SVPWM frequency conversion speed regulation system which took DSP chip as controller,introduced hardware structure of the system and its software realization,built up simulation model of the system and then did simulation test to the system with Matlab/Simulink software.The simulation results confirmed that the system had fast starting,small over shoot and small steady-state torque ripple,as well as good static and dynamic performance.
