论文摘要
传统上是单独设计的网格转换器的主动和反应性电源控制器，这取决于循环解耦的假设。本文提出了针对网格形成转换器的电源循环的全州反馈控制。首先，考虑其自然耦合，对功率回路进行了建模，因此，该耦合可以应用于各种线阻抗，即电阻，电感或复杂。然后使用全州反馈控制设计。通过这种方式，可以任意将系统的特征值放置在电源循环时间范围内的任何位置。因此，可以通过预定义的规范直接选择参数。本文还给出了分步参数设计过程。实验结果验证了提出的方法。
The active and reactive power controllers of grid-forming converters are traditionally designed separately, which relies on the assumption of loop decoupling. This paper proposes a full-state feedback control for the power loops of grid-forming converters. First, the power loops are modeled considering their natural coupling, which, therefore, can apply to all kinds of line impedance, i.e., resistive, inductive, or complex. Then a full-state feedback control design is used. By this way, the eigenvalues of the system can be arbitrarily placed to any positions in the timescale of power loops. Therefore, the parameters can be directly chosen by the predefined specifications. A step-by-step parameters design procedure is also given in this paper. Experimental results verify the proposed method.
