针对传统整流所带来的电网侧功率因数低和电流波形畸变严重等问题，提出了将迭代学习控制算法应用于整流器中，并设计了迭代学习控制器。通过对PWM整流器的建模与分析，可知开关器件的等效电阻和频率等参数的不确定会使得控制系统的稳态性能变差。仿真结果表明，将迭代学习控制应用于PWM 整流器波形控制中，可以有效改善整流器的稳态性能和降低交流侧输入电流谐波畸变率。

As the low power factor,serious current distortion and other issues to the grid side brought by traditional rectifier,the iterative learning control algorithm was put forward to be applied to PWM Rectifier,and the iterative learning controller was designed. Through the modeling and analysis of PWM rectifier,we can find that the uncer-tainty of equivalent resistance,frequency and other parameters of switching device will make the steady-state per-formance of control system poor. From the simulation results,we can find that the application of iterative learning control to PWM rectifier waveform control can improve the static behavior and reduce the input current harmonic distortion of AC side of rectifier effectively.
