Abstract

In this study, a DC-DC buck
converter circuit which is used to get direct voltage by decreasing the source
voltage is researched. Firstly mathematical model for a DC-DC buck converter
circuit is obtained and critical inductance value is calculated to make it work
in continuous current mode. Then for controlling a DC-DC buck converter, three
different controllers in discrete time (sliding mode control,
proportional–integral–derivative controller and linear quadratic regulator) are
designed. Finally, the performance of these controllers according to changing
in the form of step function for input voltage, reference voltage and load
conditions are examined and compared with real time studies. According to
obtained results, a DC-DC buck converter circuit controlled by sliding mode
controller has shown a better performance compared to the other controllers.
