摘要:

有源电力滤波器的电流控制器设计直接影响电流谐波的补偿效果，采用比例积分PI控制跟踪交流信号时存在静差，而基于内模原理的重复控制在特定频率处有无穷大的增益，能够实现电流无静差跟踪，但系统动态响应速度慢。因此，该文提出将PI前馈控制与重复控制相结合的改进重复控制方法。该方法能够对电流进行无静差跟踪，且对系统谐波具有较好的抑制效果。通过Matlab/Simulink仿真软件和APF装置验证了系统对电流谐波具有较高的补偿精度且系统的动态性能较好。

Abstract:

The current controller design of active power filter(APF) affects the compensation performance of current harmonics directly; the conventional proportional(PI) integration control is unable to track sinusoidal signals without steady-state error and the repetitive control based on the internal model principle can track sinusoidal signals without steady-state error, since it introduces infinite gain at the sinusoidal frequencies. However, the dynamic response of repetitive control is slow. Therefore, this paper proposes an improved repetitive control method,which combined PI feedforward control and repetitive control; the method can track current without steady-state error and has a good inhibitory effect on system harmonics. Through the Matlab/Simulink software and APF device, it is proved that the system has high compensation accuracy for current harmonics and the dynamic performance is better.
