中文摘要

本文提出了一种新型无差拍控制器设计,在不牺牲性能的前提下增强了鲁棒性。传统无差拍控制依赖反馈线性化且增益极高,对参数不确定性高度敏感。本文通过微分平坦理论优化设计,有效提升了系统在参数波动下的控制稳定性与动态响应能力。

English Abstract

The present contribution introduces a new deadbeat controller design that increases robustness without compromising performance. In conventional deadbeat control, feedback linearization is applied, and the feedback gains are set very high to obtain the minimum-step reference response. This makes the control method highly sensitive to parametric uncertainties. To date, the only remedies have been t...

该研究提出的改进型无差拍控制算法对阳光电源的核心产品线具有重要参考价值。在光伏逆变器(如组串式逆变器)和储能变流器(如PowerTitan系列)中,无差拍控制常用于电流环以实现快速动态响应。然而,电网阻抗变化或滤波器参数漂移常导致传统无差拍控制失稳。引入微分平坦理论设计的鲁棒控制器,可显著提升阳光电源产品在弱电网环境下的并网稳定性,减少对精确模型参数的依赖,从而提升iSolarCloud智能运维平台下设备的运行可靠性与电能质量。
