In this project, a new algorithm of maximum power point tracking (MPPT) for photovoltaic is proposed. The algorithm is based on simpilified fuzzy logic controller (FLC). The simplified FLC has one input, which is derived from the signed distance method. Due to the single-input FLC, the number of rules and tuning parameters are significantly reduced. Thus, simpler design and faster computation are expected using the simplified FLC. The simplified FLC MPPT is compared with conventional FLC MPPT. Both algorithms are implemented in stand-alone PV system that uses boost-converter. The stand-alone PV system with the algorithms are designed in MATLAB software and simulated. Result shows that the simplified FLC has similiar performance with conventional FLC. Both MPPT algorithms tracked maximum power point vary fast. Eventhough their performance are same, simplified FLC present some advantages such as simplicity of tuning of membership function, the control rule is built in one-dimensional space, the computational complexity is reduced and faster ans so on.
