A fractional order maximum power point tracker: Stability analysis and experiments

This paper presents a fractional order extremum seeking control scheme for maximum power point tracking tasks to better accommodate rapid varying solar irradiance for photovoltaic (PV) arrays. The stability analysis of the proposed control algorithm is presented first. Then the new algorithm is benchmarked against the integer order extremum seeking control. Our extensive simulation and experimental results show that, our proposed maximum power point tracker has faster convergence speed in comparison with integer order one.
