C. Adaptive P&O-Fuzzy Logic Control
This method uses existing inputs of P&O algorithm such
as differential power and differential voltage. The proposed
change in this algorithm is to replace comparing and switching
methods with fuzzy logic approach, as shown in Fig. 5. Same
four categories of FLC with new inputs are used as shown in
Fig. 6. Five proposed variables are N (Negative), ZE (Zero),
PS (Positive small), P (Positive), and PB (Positive big). Fig. 7
