The aim of this paper is to study and to compare between two control strategies for tracking the Maximum Power Point (MPP) for a photovoltaic (PV). The PV array is connected to the load through a boost converter. In fact, the Maximum Power Point Tracking (MPPT) is achieved by using two different methods for searching the Maximum Power point (MPP). These strategies methods are Perturb and observe (P&O) and Extremum Seeking Control (ESC). The aim goal of these strategies is to predict the maximum power point. Simulation results show the effectiveness of the control strategies applied to the studied system.
