In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外,为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差,本文在无差拍控制器的基础上,又提出了基于无差拍和重复控制的复合电流控制器。
