Hybrid control of a solar tracking system using SUI-PID controller

Solar energy can reduce the need of fossil fuel and ensures energy security for many countries. Solar tracking significantly improves the collection of solar energy by reducing the angle of incidence on the collecting surface. The present research introduces an optimized solar tracking system that enhances the output power of photovoltaic panels. The tracking system implements a hybrid control strategy. The system aims at maintaining a maximum output power of the panels during the day with a minimum required driving energy. It implements a Multi-Degree of Freedom-Simplified Universal Intelligent PID controller (MDOF-SUI PID) to track the sun rays. The impact of the MDOF-SUI PID controller on the Sun tracking accuracy is evaluated in the present work.
