摘    要:重复控制是改善非线性负载下输出电压波形的一种有效技术。但在逆变电源中,由于模型的不精确,常规重复控制器设计不适合于电源系统。针对模型的不精确,提出了新型的改进重复PD控制器。首先分析了重复控制器的基本原理,其次给出了改进重复PD控制器设计的具体步骤。该控制运用到一台400 Hz,5.5 kW的逆变器上,实验结果表明,该方案可得到稳态时较小的谐波畸变和突变负载时的快速响应。

关 键 词:重复控制  PD  逆变器

Abstract:Repetitive control is a good scheme to improve the voltage waveform under a nonlinear load.But the conventional repetitive controller is not fit for inverter for inaccurate mathematical model of inverter.So a new modified repetitive PD controller is presented.The principle of repetitive control is firstly described.Secondly,the design of a modified repetitive PD controller for inverter is shown.The control scheme is implemented in a 400 Hz,5.5 kW inverter,the results proved that the proposed control scheme can achieve not only low THD during steady state operation but also fast transient response subject to load step change.
Keywords:repetitive control PD inverter
