铅酸蓄电池快速充电模糊控制技术研究

针对铅酸蓄电池充电过程具有非线性、时变性、滞后性的特点,提出模糊控制充电的思想,设计了双输入/单输出模糊控制器。确定充电模糊控制器的总体结构以及模糊输入和模糊输出,建立了模糊控制规则表,给出了推理步骤以及反模糊化方法,构建了快速充电系统。实验证明,采用新型控制策略的充电方法对蓄电池充电,可减少充电时间,提高充电效率,具有重要的实际意义和推广价值。

Fuzzy Control for Lead-Acid Battery Fast Charging

An idea of fuzzy control charge is proposed aimed at non-linear, time-varying and delay in the process of lead- acid battery fast charging,a fuzzy controller of dual-input and single output was designed. The overall structure, fuzzy input and output of the fuzzy controller were ascertained, the fuzzy control rules table was built, the inference process and defuzzifi- cation means was proved, the fast charging system was conceived. The experiment shows that the charging method with new control strategy can reduce the charging time and improve the charging efficiency for the battery charging. It has important practical significance and application value.
