Switching Control based on Achievement of Maximum Power in Solar Cell with Adaptive Controller

In this paper by using the nonlinear structure for model the solar cell, the voltage and the desired power as the solar cell output are provided. The optimal operating point for power of solar cell system is called the maximum power point and varies in different conditions. In order to achieve this goal, the DC / DC converter is boost converter, which controls by its switching. Fuzzy theory has been used to achieve optimal power for load and maximum solar cell power. In this paper, the fuzzy algorithm is also used to optimize the control method. Changes in output load and amount of sunlight are among the issues in which the stability of the control system is analyzed. The results are presented according to the simulation in MATLAB software and the good performance of the controller is shown in different conditions of the system's performance.
