利用MATLAB SIMULINK仿真软件，对正弦三角波脉宽调制（SPWM）、三次谐波脉宽调制（THPWM）和空间矢量脉宽调制（SVPWM）三种不同的脉宽调制（PWM）技术进行了异步电动机的V/F控制。异步电动机在同步q-d坐标系下的建模。IM与满载转矩的性能进行比较，使用这些技术的总谐波失真，谐波频谱，直流电源电压的利用率，输出电压的基波峰值和电机转速。研究了参考转速和负载转矩变化时SVPWM永磁同步电机的动态性能。仿真结果表明，SVPWM具有上级特性，是一种有效的PWM控制方法。采用SVPWM技术后，闭环系统的电压/频率法IM运算量得到了提高。关键词：空间矢量调制，SPWM，V/f控制，谐波注入。
This paper presents a v/f control of induction motor with different pulse width modulation ( PWM) techniques as sine triangle pulse width modulation ( SPWM), Third-harmonic pulse width modulation (THPWM) and Space vector pulse width modulation(SVPWM) using MATLAB SIMULINK. Induction motor modeled in the synchronous q-d reference frame. The performance of IM with full load torque is compared using these techniques for THD, harmonics spectra, utilization of dc supply voltage, fundamental peak of the output voltage and motor speed. The dynamic performance of IM using SVPWM under reference speed and load torque variations is studied also. The results show that the SVPWM is the efficient one because it’s superior performance characteristics. The operation of IM with v/f method for closed loop system is enhancement when SVPWM technique is applied. Keywords: Space vector modulation, SPWM, V/f control, Harmonic injection.
