Abstract: The movement of the earth leads to constant change in the intensity and the angle of solar irradiation. As a consequence, the cells of photovoltaic (PV) modules are only able to convert a fraction of the light energy from the sun into electric energy. A tracking system constantly adapts the angle of PV modules to face the sun, so that the irradiation angle and the light intensity remain constant and a maximum of electrical energy can be generated. This not only helps to exploit every minute of sunshine but also to make the best use of diffuse light all year round. The aim of this research is to design a robust tracking control system that will point the PV modules to the brightest point in the sky. This objective is achieved by the design of a specialized robust controller and application of the D-partitioning analysis method.
