A comparitive study of youla and PID control algorithms for regulation of output voltage of Buck converter

The switched mode dc-dc converters are some of the simplest power electronic circuits which have received an increasing deal of interest in many areas due to their high efficiency and small size. These converters are non-linear and time-variant in nature; hence the analysis, control and stabilization are the main factors that need to be considered. Many control methodology are used for control of switch mode dc-dc converters but the optimum one is always in demand. This paper presents the linearization of the Buck converter model and a comparison between the control algorithms for better output voltage regulation along with robustness to change in input voltage and load parameters. The computer -aided design software tool Matlab/Simulink is used for the simulations and the results are presented.
