Neetu Sharma , Dr.Pradyumn Chaturvedi , Rahul Dubey. "Comparative Study of PI Controlled and Fuzzy Controlled Buck Converter". International Journal of Engineering Trends and Technology (IJETT). V4(3):451-457 Mar 2013. ISSN:2231-5381. published by seventh sense research group.


The main objective of this paper is to compare the performance between fuzzy controller and proportional integral controller in improving the performance of the DC - DC Buck Converter. The evaluation of the output has been carried out and compared by software simulation using MATLAB. This paper also evaluates the stability of the system with fuzzy controller and PI controller and concludes that the fuzzy controller is able to achieve faster transient response, has major stable steady state response and is more robust under different operating points .
