| 摘 要： | 针对并联型有源电力滤波器(APF)的直流侧电压波动对谐波电流补偿影响的问题,研究利用高阶微分器(HOD)构成高阶微分反馈控制器(HODFC)替代传统PI控制器,对并联型APF直流侧电压进行控制。通过HOD可以高品质地提取输入信号和输出信号以及其一阶微分和二阶微分,结合一定的控制律实现对APF的HODFC控制。仿真结果表明该控制策略具有可行性,与传统PI控制比较,具有良好的静态和动态性能,可使并联型APF直流侧电压在不到1/2个电源周期中就达到稳定,同时电流畸变率从24.49%降到2.31%,能显著改善电网质量。

| Abstract: | For the problem that the DC-side voltage fluctuations of parallel active power filter(APF) compensated the harmonic currents,a high order differential feedback controller(HODFC) was designed with the high order differentiator(HOD) to alternate the traditional PI controller and control the DC-side voltage of parallel APF.The input and output signal and their first and second order differential could be high-quality extracted by HOD,together with some control law,the control of HODFC could be achieved.The sim... |
