摘要: 针对传统的永磁同步电动机驱动器采用正弦脉宽调制技术存在直流母线电压利用率不高的问题，提出了一种基于SVPWM的永磁同步电动机控制系统的设计方案；分析了该系统的工作原理，详细介绍了SVPWM算法的实现，并给出了该系统的硬件及软件设计。实验结果表明，该系统启动速度快，运行稳定。Abstract: In view of problems that utilization coefficient of DC bus voltage is not high in traditional driver of PMSM which uses sine pulse width modulation technology, the paper proposed a design scheme of control system of PMSM based on SVPWM. It analyzed working principle of the system and expounded implementation of SVPWM algorithm, and gave design of hardware and software of the system. The experiment result showed that the system has quick starting speed and reliable running.
