Extraction of maximum power from photovoltaic system using fuzzy logic control

Maximum power point tracking (MPPT) algorithms plays an important role in improving the performance of photovoltaic system. A fuzzy based MPPT algorithm is proposed with current controlled DC-DC converter. Two input and single output Sugeno fuzzy system with triangular membership function is used to generate the control current. The proposed method is implemented in MALAB and the maximum power tracking performance is evaluated. The performance of proposed method is compared with conventional perturb and observe (P&O) algorithm and without MPPT technique. The proposed method tracks the maximum operating point with no oscillation and improved accuracy. The simulation results prove the effectiveness of the proposed method.
