耦合模糊PID控制的蓄电池充电研究

Battery charging based on coupling fuzzy PID control

立足于解决蓄电池在传统充电模式下使用效率低及循环寿命短问题,结合模糊PID控制策略与耦合控制方法,使得充电过程中各单体蓄电池在充电电流有动差的情况下,转换成主从关系,使主充电蓄电池的充电电流对从充电蓄电池的充电电流进行跟踪,以消除充电电流的动差,从而达到同步、等值、限流充电的目的。利用Matlab对此过程进行了仿真,结果达到了预期目的。

In order to improve the poor charging efficiency and short cycle life of battery under the traditional charging mode, combined fuzzy PID control with coupling control method, the process of charging the single cell under the current moment was converted to master-slave relationship, so that the main charge battery charging current from the charge battery charging current track to eliminate the moments of the charge current to achieve synchronization, equivalent to a constant-voltage current-limiting charging function. The process was simulated by Matlab and the results reach the expected goal.
