中文摘要：

大量电力电子设备的使用，导致电网中产生了一系列的谐波。针对谐波抑制方法，提出了一种集无差拍控制和改进型重复控制于一体的复合控制策略，实现对p肚1次谐波的高效补偿。依据有源电力滤波器（ActivePowerFilter,APF）的数学模型，推导出应用于有源电力滤波器的无差拍控制算法；提出一种改进型重复控制，缩短工频延时，通过调节内模P的值，抑制pkil次谐波；详细研究了复合控制的设计方法。将无差拍控制和复合控制进行仿真对比和实验验证，经滤波后网侧电流畸变率分别降至7．8％和2．8％。该结果表明，复合控制可以效地补偿谐波，改善波形质量，同时满足稳态精度和动态性能的要求。

英文摘要：

The wide application of power electronic equipment makes harmonic problem become increasingly serious. The deadbeat control combined with repetitive control are utilized to realize the high efficiency compensation for pk~l harmonics. The deadbeat control is deduced by mathematical model in order to control different harmonics, and a repetitive control is proposed to eliminate periodic steady-state error and shorten frequency delay through adjusting the value of the internal model p. The results of simulation and experiments demonstrate the effectiveness of current control for APE the total harmonic distortion values of source current by deadbeat control and compound control reduce to 7.8% and 2.8%. The compensation meet the requirements of the higher precision and better dynamic performance.
