A fuzzy-based technique is described for the maximum power position (M-PP) following for a system with the variable insolation. The considered system consists of a solar array with a boost converter. The proposed approach was analyzed with the perturb and observe (PO) technique and incremental conductance (IN-Cond), which is extensively used from all traditional techniques for M-PP following. All strategies were modelled and analyzed in MATLAB/Simulink. The results gone show that the fuzzy method provides a good, also greater dependable technique.
