摘　　要：依据蓄电池充电过程的非线性、时变特性,提出了与蓄电池充电特性匹配的,结合Cuk变换电路、模糊算法的模糊控制充电方法。实践证明:Cuk变换电路可以有效地减小输入和输出端电流的脉动,模糊控制使充电时间由17小时缩短到15.5小时,并且能够自动工作在最大充电电流状态,提高了充电效率;系统工作稳定性好,充电效果较三段式充电得到改进;可以延长蓄电池的使用寿命,实用性强,适于推广使用。According to the charging of the battery, a fuzzy control method is proposed that match with battery characteristics, combined with Cuk converter circuit and fuzzy algorithm. It is proved that Cuk converter circuit can effectively reduce the ripple of input and output, the fuzzy control make the charging time from 17 hours to 15.5 hours, and can automatically work in the maximum current, efficiency is improved. System work better and stably than the three--stage charging in the practice, it is suitable for promotional use.
