Solar Tracking Fuzzy Control System Design using FPGA

Abstract

Abstract—A solar tracking generating power system is designed and implemented. An expert controller, sensors and input/output interface are integrated with a tracking mechanism to increase the energy generation efficiency of solar cells. In order to track the sun, cadmium sulfide light sensitive resistors are used. To achieve optimal solar tracking, a fuzzy algorithm is developed. A field programmable gate array is applied to design the controller such that the solar cells always face the sun in most of the day time. Index Terms—solar tracking, two-axis tracking, field programmable gate array, fuzzy control. I.
