摘要

建立了三相四线制有源滤波器的完整数学模型。针对三相四线制有源滤波器，提出了一种基于重复预测型谐波电流观测器的新型无差拍控制方案，以改善有源滤波器的动态性能。详细阐述了新型无差拍控制的原理、控制系统的离散化模型、重复预测型谐波电流观测器的工作原理及保证其稳定工作的充分条件。基于MATLAB/Simulink的有源滤波器控制系统仿真分析表明，所提出的新型无差拍控制方案在保证系统稳态精度良好的同时有效改善了系统的动态响应。

Abstract

The complete mathematical model is established for three-phase four-wire active power filters（APF）. A novel deadbeat control scheme based on repetitive harmonic predictor is proposed to improve the dynamic performance of three-phase four-wire APFs. The principle of the novel deadbeat control scheme， the discrete time model of the control system and the working principle of the repetitive harmonic predictor are presented in detail.The sufficient condition for keeping the repetitive harmonic predictor stable is also discussed in the paper. The MATLAB/Simulink based simulation analysis of the APF control system shows that the dynamic response of the control system is effectively improved and the steady state accuracy is good enough by implementing the novel deadbeat control scheme.
