智能UPS控制技術研究

摘要：本文詳細分析了常規PID控制和基于PID控制和重復控制的復合控制的優缺點。并在實驗樣機上做了對比實驗，結果表明基于PID控制和重復控制的復合控制策略具有優良的控制效果，對各種負載輸出電壓諧波失真度滿足要求。 敘詞：PID控制；重復控制；諧波 Abstract：This paper focus on two control strategies for intelligent UPS. After analyzing the performance of this two control strategies, above two control strategies have applied to 10KVA inverter module. It can be seen from the experiment that the compound control strategy based on PID and repetitive control performs good dynamic and static performances.
