A Survey On Optimal Tuning Of PID Controller For Buck-Boost converter Using Cuckoo-Search Algorithm

The concept of global warming has become a very big issue due to the rise in the level of consumption of energy. So the increased efficiency rate of consumption of energy is an inevitable factor in our modern society. Many applications is in need of a high efficient system. So inorder to attain high efficiency, commonly dc-dc converters are being used. This paper reveals the study of various dc-dc converters and the controllers which is used to control the dc-c converters for efficient applications. Among the different dc-dc converters, the buck-boost converter is special because it has both step-up and step-down modes. So a study of various buck-boost converters was carried out and the simplest and most efficient with fewer losses was found. A survey on various control technique that can be used for efficient control of the buck-boost converter was done. PID controller technique was deeply studied and different tuning algorithms was analyzed. These algorithms was compared with each other by considering their performance and optimization ability in limited time period.
