模糊控制在光伏系统充电控制中的应用

FUZZY CONTROL APPLICATION FOR CHARGE CONTROL IN PV SYSTEM

在光伏系统中 ,太阳电池的输出、蓄电池的负载及蓄电池的自放电均为不确定量 ,用经典控制理论往往不能达到很好的充电效果。该文将模糊控制理论运用到光伏系统充电控制中 ,并利用MATLAB进行仿真 ,达到了较好的充电效果。

In a PV system, the output of solar cells, the load and the discharge of accumulators are indefinite quantities. Generally, it can not obtain a satisfied effect in controlling the charge of accumulators by using the classic control methods. In this paper, fuzzy control theory is applied in the charge control in PV system, the emulation result from the MATLAB language shows that the proposed system achieves an exciting result.
