摘　　要：比较了SPWM技术和SVPWM技术的优缺点,证明了SVPWM调制技术具有最高的直流电压利用率。对两种调制方法下逆变器控制的PMSM速度和电流双闭环控制系统性能进行了仿真比较研究。借助于dSPACE实时平台,完成了两种调制方式下PMSM控制系统的硬件在回路试验。试验结果进一步表明,与SPWM调制方式相比,SVPWM调制技术具有更好的动、静态性能与鲁棒性,更适合于高性能PMSM伺服系统的控制。Compared with the traditional SPWM,SVPWM has the highest DC voltage utilization ratio.The comparison study of PMSM speed and current dual closed-loop control system based on two kinds of PWM technology was achieved by Simulink.Finally,the hardware in loop（HIL） real-time simulations of PMSM speed and current dual closed-loop control system based on two kinds of PWM technology was completed by dSPACE system to further verify the better dynamic response and robustness of SVPWM,which is more suitable for high-performance PMSM servo control system.
