A Sliding Mode Multimodel Control for a Sensorless Photovoltaic System

This study presents a sliding mode multimodal control for a sensorless photovoltaic panel, which sets itself as per the sun position at every second during the day for a period of five years; then tracker, using sliding mode multimodal controller and a sliding mode observer, will track these positions to make sunrays orthogonal to photovoltaic cell that produces more energy. After sunset, tracker goes back to initial position of sunrise. This autonomic dual axis sun tracker increases power production by over 40%.
