| 摘 要： | 交流电动机的变频调速技术应用愈加广泛,但在变频器的输出电压中含有大量的谐波,为有效地消除谐波的不利影响,在传统的规则采样法的基础上对其进行改进,提出一种新型的采样法.应用Matlab/Simulink建立变频调速系统的仿真模型,仿真实验表明,该采样法能更精确地确定采样点的开关时刻,有效地抑制谐波,使谐波畸变率达到5%以下.

| Abstract: | Frequency control technology of AC motor is more widely,but the output voltage of transducer contains a large number of the harmonic.In order to eliminate harmonic effectively of the traditional sampling method,a new type of sampling method is put forward.The simulation model of frequency controlling is established by using Matlab.The simulation results demonstrate that the method can confirm the time of on-off of sampling points accurately and restrain the harmonic effectively,which makes the harmonic dist... |
