Extremum Seeking Control (ESC) for Maximum Power Point Tracking (MPPT) of Photo-Voltaic system

Extremum Seeking Control Algorithm is employed to seek the max/min point of nonlinear functions

In this simulation a new MPPT approach called "Extremum Seeking Control (ESC)" has been employed to seek the peak power point of a PV system. According to various researchers, a well tuned ESC has a better efficiency compared to other MPPT algorithms like P&O or IC. For more information regarding the operation of ESC please review
