摘　　要：针对单相脉宽调制(PWM)整流器的输入电流控制提出了鲁棒重复控制方案,并详细给出了该方案的设计方法。所提出的控制方案将鲁棒优化反馈控制与重复控制有机结合,实现了二者优势互补。实验结果表明:采用鲁棒重复方案控制的单相PWM整流器不仅能输出高质量的输入电流,总谐波畸变率低,跟踪精度高,动态响应快,而且对参数变化和负载扰动具有很好的鲁棒性。A robust repetitive current control scheme is proposed for the input current of single-phase pulse width modulation（PWM） rectifier, and the design procedure of robust repetitive control scheme is presented.The proposed control scheme appropriately combines robust feedback control with repetitive control, and can achieve their advantages complement.Experimental results demonstrate that robust repetitive control single-phase PWM rectifier can produce high quality input current with low total harmonic distortion, high tracking accuracy,fast dynamic response, and has good robustness under load disturbances and parameter variations.
