Considerations of Extremum-Seeking Control based on the Sinusoidal Perturbation Applied to the MPPT Converter with PWM Modulation

This article analyzes the extremum-seeking control based on sinusoidal perturbation applied to a maximum power point tracking (MPPT) converter with pulse width modulation (PWM). With the proposed algorithm it is possible for the MPPT converter to track the optimal set point, with a fast transient response, as evaluated through simulation results. Further details involving the proposed control algorithm and the MPPT converter performance were discussed throughout this paper as well.
