| 摘 要： | 采用GM（1,1）模型设计了一种灰色预测,能准确地预测下一开关周期中所需电量,包括交流输入电压、直流输出电压、升压电感电流、升压电感电流偏差和直流输出电压偏差,实现精确控制。将采用开关周期的电压偏差和电流偏差分别与预测电流偏差和输出直流电压偏差相加,实施重复控制,消弱静差和改善动态特性。制订了基于灰色预测和重复控制的两电平功率因数校正的综合控制策略,并进行了试验研究,试验证明了所提方案的正确性。

| Abstract: | A grey prediction using GM （ 1,1 ） model was designed ,which could accurately predict the required power in the next switching cycle, including the AC input voltage, the output DC voltage and the Boost inductor current, realizing accuracy control. The voltage deviation and current deviation in the current switching cycle could be added to the predicted current deviation and output DC voltage deviation respectively, repetitive control was implemented,to reduce the static error and improve the dynamic characteristics. A novel comprehensive control strategy was presented based on grey prediction and repetitive control. Experimental studies were conducted, and the results show the strategy is correct. |
