| 摘 要： | 针对PI控制存在的对周期性扰动抑制能力差的问题，提出了在 PI控制的三相 PWM整流器三闭环控制系统中引入重复控制的方法。通过将原有PI控制与重复控制相结合，不仅提高系统的稳态精度，同时兼顾了三相 PWM整流器的动态性能，有效地抑制了周期性干扰对输入电流和直流母线的影响。详细介绍了三相 PWM整流器的 PI 控制与重复控制结合的控制方法，并通过仿真验证了改进后系统的稳态特性有较大的提升。

| Abstract: | According to the problem that PI control method can hardly restrain the periodic interference,repetitive control method have been introduced to the control of three-phase PWM rectifier.Through the combination of the PI con-trol method and the repetitive control method,not only the stable precision of the system can be improve,but also the dy-namic performance can be balanced.The method can effectively restrain the effect of the periodic interference to the input current and DC voltage.The paper introduces the method of the combination of the PI control method and the repetitive control method in detail,and the improvement of steady-state performance of the system have been verified by the simula-tion. |
