MPPT based on Newton-Like Extremum Seeking Control

Overview of Maximum Power Point Tracking Techniques for Photovoltaic Energy Production Systems

“…ESC is a self-optimizing control strategy [51] that operates based on a similar principle with RCC MPPT; the difference is that instead of using the high-frequency switching ripple, which is inherent in the power converter, ESC is based on the injection of a sinusoidal perturbation [52][53][54][55]. The block diagram of an ESC scheme based on the method presented in [55] is shown in Figure 12 output power p(t) is passed through a high-pass filter and demodulated.…”
