REALIZATION OF CLASSICAL AND NON LINEAR CONTROLLERS BASED MPPT TECHNIQUES FOR PV SYSTEM

Abstract

This project presents the collective study of various Maximum PowerPoint Tracking Methods. These methods include widely used MPPT techniques such as Perturb and Observe (P&O), Incremental Conductance (InC) & Sliding Mode Approach (SMC), Backstepping Controller (BSC) with integral action. Maximum Power Point (MPPT) Tracking is essential to obtain the optimum power from a photovoltaic system otherwise a substantial amount of power is wasted. This work is focused on the testing of these methods under varying irradiation conditions. Conventional methods like Perturb and Observe (P&O) and Incremental Conductance (InC) are easy to implement but they show oscillations around Maximum power point under varying irradiations condition, non-linear tools like Sliding Mode Control (SMC) approach and Backstepping Controller (BSC) with integral action are used to ensure the reduction in these oscillations.
