中文摘要

本文针对传统基于离散傅里叶变换的重复控制器(DFTRC)在动态响应慢、控制结构缺陷及频率波动敏感性方面的不足,提出了一种增强型控制策略。该方法提升了选择性谐波补偿的性能,增强了系统在复杂电网环境下的稳定性和动态调节能力。

English Abstract

Among the various selective harmonic current controllers, the traditional repetitive-based discrete Fourier transform controller (DFTRC) is increasingly favored thanks to its unique merits of excellent selectivity and simplicity. However, the traditional approach suffers from disadvantages like slow dynamic responses, defective control structure, and sensitivity to frequency fluctuation. In order ...
