| 摘 要： | 该文将重复控制和状态反馈方法用于一种混合有源电力滤波器中的电压源型逆变器的输出电流波形控制，其中状态反馈环节保证了系统的稳定性，而重复控制环节提高了输出电流波形的跟踪精度。文中详细分析了控制器的设计思路和频率特性。实验结果表明采用该方法后，可以取消逆变器输出滤波器中的电阻元件，减小运行损耗，同时显著改善滤波效果，适合于高电压大电流场合的谐波治理。

| Abstract: | The paper adopted state feedback and repetitive control algorithm to correct the output current waveform of the voltage source inverter in a hybrid active power filter(HAPF). In this control strategy, the state feedback loop is used to guarantee system stability and the repetitive control loop is to improve current waveform quality. The controller design procedure and frequency characteristic are analyzed in detail. By this control method, the resistance of the inverter output filter can be cancelled, the HAPF operating loss is decreased and filtering performance is ameliorated. So it is suitable for harmonic compensation in high voltage and large current condition. Theoretical analysis is verified by experiment results. |
