摘要 并网逆变器中比例多谐振控制器能够同时抑制多个频率的入网电流谐波。为了解决传统比例多谐振控制器设计复杂,并联谐振控制器个数有限的问题,该文提出一种基于重复控制和比例控制的新型重复-比例复合控制器,该复合控制器只需要设计少数几个控制器参数。首先,根据重复控制器频域展开式,推导出重复-比例复合控制器可以由重复控制器和比例控制器并联构成;其次,分析新型重复-比例复合控制器的稳定性及参数设计理论依据;最后,以L型单相并网逆变器为被控对象,给出复合控制器的参数设计流程。实验结果验证了该文提出的复合控制器能够同时抑制多个频率的电流谐波,并具有快速的动态性能。

Abstract:The proportional multi-resonant (PMR) controller in a grid-connected inverter can simultaneously suppress many harmonics in input current of grid. However, the traditional PMR is complex designed and has limited number of parallel resonant controllers. Therefore, a novel combination controller based on repetitive control (RC) and proportional control (PC) is proposed in this paper, which only needs to design a few parameters. Firstly, according to the expansion of RC in frequency domain, the novel combination controller can be realized in parallel of RC and PC. Then, the stability and parameter design of the proposed controller are analyzed. Finally, the parameters of the novel combination controller in L-type grid-connected inverter are designed. The experimental results show that the proposed combination controller can simultaneously suppress harmonics of multiple frequencies and has fast dynamic performance.
