In operation of MPPT control, after E and CE are
calculated, these inputs are converted into linguistic variables
and then the output D is generated by looking up in a rule-base
table. The FLC tracks the MPP based on master rule of “If X
and Y, Then Z” [3, 12]. To determine the output of the fuzzy
logic, the inference is used. There are many methods for
inference but the popular one is Memdani [3, 6].
