Fuzzy Controller Based MPPT Technique for Extraction of Maximum Power from a Solar PV System

Boost Converter,Maximum power point tracking,Perturbation and observation,, PV Modelling

Two types of MPPT techniques are focused in this paper i.e. the conventional Perturb and Observation method and fuzzy logic controller. It is seen that the tracking speed of fuzzy logic controller is consistent and improved as compared to the conventional P&O controller. However, the disadvantages of P&O controller is that it has very poor dynamic response and the operating point keeps swinging around the maximum power point during steady state operation. So in this paper the emphasis is given to the fuzzy logic controller design and it is being compared with the P&O controller . The algorithm implemented here was used to track the maximum power of a day. The implementation used a fuzzy logic controller and using a DC-DC converter to keep the PV output power at the maximum point all the time. All the simulation are done using MATLAB/SIMULINK
