Design and Implementation of an Optimized Sliding Mode Controller and Compared with a Conventional MPPT Controller for a Solar System

Authors: , , , ,

Abstract: This article gives a broad idea about Sliding Mode Controller (SMC) implementation to a DC-DC Boost Converter for a Photovoltaic (PV) system to track Maximum Power Point (MPP). SMC implementation meets three conditions like (i) Hitting, (ii) Existence and (iii) Stability. Single exponential PV model is designed for lighting applications, and PV output is connected to a Boost converter to regulate and increase the voltage up to desired level. SMC is implemented in a feedback manner with capacitor voltage and inductor current. The steady state condition occurred at around 0.1sec, and tracking 1.13% extra power at Standard Test Conditions (STC). The results of SMC are compared with Incremental conductance (Inc Cond) Maximum Power Point Tracking (MPPT) controller; the models are simulated in MATLAB/SIMULINK.
