Fuzzy Logic based Control Technique using MPPT for Solar PV System

This paper proposes a fuzzy logic based maximum power point tracking (MPPT) controller to track the maximum power from PV panel. Solar PV arrays have nonlinear I-V characteristics and are affected by factors like temperature and irradiance. In this paper, the fuzzy MATLAB Simulink is used to implement MPPT controller using fuzzy logic technique. Fuzzy logic MPPT model has ability to handle nonlinearity nicely and is capable of tracking the maximum power more precisely and rapidly. It provides overall better performance as compared to conventional techniques in terms of maximum power point tracking.
