摘要

重复控制器是改善非线性负载下输出电压波形的有效技术。论述了重复控制的原理并分析了重复控制的优缺点,介绍了针对数码发电机中逆变模块的重复控制器的设计方法和步骤,并利用Matlab/Simulink软件进行仿真研究,结果表明,重复控制器具有良好的控制效果,能够有效减小输出电压的谐波含量。%Repetitive control （RC） is the valid technology to improve voltage output waveforms under nonlinear load. This paper discussed the principle of RC and analyzed the performance of repetitive control. Introduction was made to the design method and steps of repetitive controller based on inverter of digital generator. Simulink in Matlab was used to simulate and research. The result shows that the repetitive controller can take control of inverter effectively and restrain the harmonic contents of output voltage availably.
