摘 要: 針對(duì)傳統(tǒng)PI 控制方法存在的超調(diào)量過(guò)大、電壓紋波問(wèn)題的缺陷,提出一種有源電力濾波器(APF) 直流側(cè)電容電壓的新型復(fù)合控制策略,即將自適應(yīng)檢測(cè)無(wú)差拍控制產(chǎn)生的誤差,經(jīng)由重復(fù)控制,從而進(jìn)一步減小控制誤差。分析比較了傳統(tǒng)的PI 控制方法與基于重復(fù)控制的自適應(yīng)預(yù)測(cè)無(wú)差拍控制方法,并對(duì)直流側(cè)電容電壓的控制進(jìn)行了仿真,結(jié)果表明了該新型控制策略的可行性與優(yōu)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
