【摘要】 在本文中,提出了一种使三相电压型PWM整流器达到零跟踪误差的z域下的重复控制策略。这种控制方案属于嵌入式结构:一个嵌入式重复控制器(RC)加一个常规控制器(如:PI或PD控制器)。文章系统性的发展了插入式重复控制器的设计。接近单位功率因数和恒定的输出确保电压在参数不确定和负荷扰动的情况下保持稳定。仿真和实验结果证明了这种控制策略的可靠性。更多还原

【Abstract】 In this paper,a repetitive control strategy is proposed to achieve zero tracking error for three-phrase voltage-source PWM rectifiers in z field.The proposed control scheme is of "plug-in" structure:a plug-in digital repetitive controller plus a conventional controller(e.g.,PI or PD controller).The design of the plug-in repetitive learning controller is systematically developed.Near unit power factor and constant output do voltage are ensured under parameter uncertainties and load disturbances.Simulation and experimental results are provided to testify the effectiveness of the proposed control scheme.更多还原
