摘 要: 针对传统PI 控制方法存在的超调量过大、电压纹波问题的缺陷,提出一种有源电力滤波器(APF) 直流侧电容电压的新型复合控制策略,即将自适应检测无差拍控制产生的误差,经由重复控制,从而进一步减小控制误差。分析比较了传统的PI 控制方法与基于重复控制的自适应预测无差拍控制方法,并对直流侧电容电压的控制进行了仿真,结果表明了该新型控制策略的可行性与优越性。

Abstract: Aiming at the defect that there exist problems of much more overshoot and voltage ripple in traditional PI control method, this paper proposed a kind of new type compound control strategy for capacitor voltage at direct current side in active power filter. The errors caused by self-adaptive detection deadbeat control were controlled repetitively to decrease the control errors further. The traditional PI control method was compared with the self-adaptive prediction deadbeat control method based on repetitive control and the control of capacitor voltage at direct current side was carried out simulation. The results show that this new type of control strategy is feasible and superior.
Key words: active power filter; control of capacitor voltage; new type compound control; simulation verification
